I basically agree that, partly due tot he nature of the web, if you place information which can be freely viewed on the web then you should expect people to save copies of it to their hard drives, and possibly share it for free, content unchanged (or with comments placed in brackets). The main stipulation would be that the source must be accredited, and should not be used to make money without the owner’s permission.
Since you have class action suits is it possible to have something similar to this for the defendants? That way all the hoards of people being sued could band together and fight this transparent shake-down attempt by this rouge law firm.
I think that a far better tactic would be to go with the "fair use" exemption.
