Hizook.com, "the robotics news portal," relates an unfortunate incident:

Hizook.com has received an amazing flurry of activity in the last 10 days.  We made it to the front page of Slashdot (twice!),  Reddit (twice!), Engadget, Makezine, Hacker News (etc, etc) — amassing well over 100,000 pageviews!  During the height of the activity, we received an email indicating that Hizook’s Google Adsense account was being disabled.  There was no further explanation, no warning, no attempt made to resolve the situation — in fact, our only recourse was to fill out a web form and hope for a prompt response.  Apparently that is indicative of Google’s customer service.  The remainder of our account is chronicled below.  But, as extremely loyal Google users (Search, Gmail, Google Voice, Google Calendar, formerly Adsense, someday Adwords) and Google share holders, we are simply… aghast.

Here is the entirety of the explanation provided by Google, at 11pm on Sunday night, when they unilaterally disabled the account:

Hello,

While going through our records recently, we found that your AdSense
account has posed a significant risk to our AdWords advertisers. Since
keeping your account in our publisher network may financially damage our
advertisers in the future, we’ve decided to disable your account.

Please understand that we consider this a necessary step to protect the
interests of both our advertisers and our other AdSense publishers. We
realize the inconvenience this may cause you, and we thank you in advance
for your understanding and cooperation.

If you have any questions about your account or the actions we’ve taken,
please do not reply to this email. You can find more information by

Sincerely,

The Google AdSense Team

I’ve made the front page of Hacker News twice — it is indeed quite a traffic spike, and, if I advertised, I would be very upset if my advertiser torpedoed me without notice at the height of the traffic.

So, can they sue?

Let’s look at the Google Adsense Terms and Conditions:

9.      No Warranty. GOOGLE MAKES NO WARRANTY, EXPRESS OR IMPLIED, INCLUDING WITHOUT LIMITATION WITH RESPECT TO ADVERTISING, LINKS, SEARCH, REFERRALS, AND OTHER SERVICES, AND EXPRESSLY DISCLAIMS THE WARRANTIES OR CONDITIONS OF NONINFRINGEMENT, MERCHANTABILITY, AND FITNESS FOR ANY PARTICULAR PURPOSE. TO THE EXTENT ADS, LINKS, AND SEARCH RESULTS ARE BASED ON OR DISPLAYED IN CONNECTION WITH NON-GOOGLE CONTENT, GOOGLE SHALL NOT HAVE ANY LIABILITY IN CONNECTION WITH THE DISPLAY OF SUCH ADS, LINKS, AND SEARCH RESULTS.

10. Limitations of Liability; Force Majeure. EXCEPT FOR ANY INDEMNIFICATION AND CONFIDENTIALITY OBLIGATIONS HEREUNDER OR YOUR BREACH OF ANY INTELLECTUAL PROPERTY RIGHTS AND/OR PROPRIETARY INTERESTS RELATING TO THE PROGRAM, (i) IN NO EVENT SHALL EITHER PARTY BE LIABLE UNDER THIS AGREEMENT FOR ANY CONSEQUENTIAL, SPECIAL, INDIRECT, EXEMPLARY, OR PUNITIVE DAMAGES WHETHER IN CONTRACT, TORT OR ANY OTHER LEGAL THEORY, EVEN IF SUCH PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES AND NOTWITHSTANDING ANY FAILURE OF ESSENTIAL PURPOSE OF ANY LIMITED REMEDY AND (ii) GOOGLE’S AGGREGATE LIABILITY TO PUBLISHER UNDER THIS AGREEMENT FOR ANY CLAIM IS LIMITED TO THE NET AMOUNT PAID BY GOOGLE TO PUBLISHER DURING THE THREE MONTH PERIOD IMMEDIATELY PRECEDING THE DATE OF THE CLAIM. Each party acknowledges that the other party has entered into this Agreement relying on the limitations of liability stated herein and that those limitations are an essential basis of the bargain between the parties. Without limiting the foregoing and except for payment obligations, neither party shall have any liability for any failure or delay resulting from any condition beyond the reasonable control of such party, including but not limited to governmental action or acts of terrorism, earthquake or other acts of God, labor conditions, and power failures.

Google obviously believes the answer is "no," and wrote their contract to prohibit any suits at all.

Yet, like with most tech companies, Google’s terms of service provide "This Agreement shall be governed by the laws of California." California is among the most consumer-friendly states in the nation.

So the question isn’t so simple:

Under UCC § 2-719(1)(b), ‘[r]esort to a remedy as provided is optional unless the remedy is expressly agreed to be exclusive, in which case it is the sole remedy.’ However, ‘[w]here circumstances cause an exclusive or limited remedy to fail of its essential purpose, remedy may be had as provided in this code.’ UCC § 2-719(2). … See id.; RRX Indus., Inc. v. Lab-Con, Inc., 772 F.2d 543, 547 (1985) (‘Under the Code, a plaintiff may pursue all of the remedies available for breach of contract if its exclusive or limited remedy fails of its essential purpose.‘).

‘A limited remedy fails of its essential purpose when the circumstances existing at the time of the agreement have changed so that enforcement of the limited remedy would essentially leave plaintiff with no remedy at all.’ Computerized Radiological Servs., Inc. v. Syntex Corp., 595 F. Supp. 1495, 1510 (E.D.N.Y. 1984), aff’d in part and rev’d in part, 786 F.2d 72 (2d Cir. 1986) (emphasis added). This theory often is raised where a buyer seeks a refund or rescission of the original agreement, but the seller insists that repair is the only available remedy. See, e.g., Gavaldon v. DaimlerChrysler Corp., 32 Cal. 4th 1246, 1259-65, 13 Cal. Rptr. 3d 793, 90 P.3d 752 (2004)."

Stearns v. Select Comfort Retail Corp., 2009 U.S. Dist. LEXIS 48367, at *16–17 (N.D. Cal. Jun. 5, 2009).

Sure seems like Hizook is left with "no remedy at all" under the contract. It thus seems they could indeed sue for direct and consequential damages, including the lost ad revenue.

The above analysis applies to goods, rather than services, but two points weigh in Hizook’s favor: first, the original RRX Indus., Inc. opinion itself found a software system to be a "good," and, second, a number of courts recognize the same analysis for service contracts, too.

Unfortunately, it’s probably not worth Hizook’s time or energy to sue over it — which is why some creative Silicon Valley lawyers should be thinking about initiating a class action. Google’s search engine shows 16,500 hits for "While going through our records recently, we found that your AdSense account has posed a significant risk to our AdWords advertisers."

As Bruce Schneier has written in the context of security software, liability changes everything. If AdSense users want Google to shape up, it seems they need to sue their way into it.
