yup.. it has been expressed to me by different folks, that WHEN the defendants get a non-infringing verdict, that all other websites will be free from the patent...
BUT, those that signed the agreement, like you said, agreed to the terms of the contract, and it is a contract, and they would have to breech the contract and then get sued by Acacia.. go to court and cite the defendants verdict....
What remains to be seen is about all the subsequent patents that Acacia has filed and whether the non-infringing verdict would help to knock out the legs of the later patents.....
