Anti-SLAPP laws exist for a reason, and if corps can bully anyone, how is it that corps routinely lose lawsuits on either side of the docket, hmmmm?
Keep licking that corporate boot, folks. Corps send C&Ds because they cost them all of maybe $100-200 and they're so effective.
There is a long road between "got a C&D" and "am getting sued." Among other things, a judge is going to want to see that both sides attempted to negotiate. If the company sending the C&D just demands that and then tries to file suit, the judge is going to tell them to go back to step 2 and stop bothering him/her.
Folks, stop telling people that if they get a C&D they have to just fold. Good chance you never hear from them again because the cost of suing you is nowhere near the damages they will be able to prove in court.
