I hope I can join in, as a consumer, because there’s a difference between using the IP I contribute to conversations for a non-profit and a commercial enterprise.
I suspect that if you have ever posted copyrightable material online, you will have valid cause to sue them, as they very obviously have incorporated your work for commercial gain. That said, I unfortunately put your chances of winning in court very low.
And why is it, that winning chances are low? Why do the courts let big tech trample on our rights, but the small man goes to jail or has to pay fines for much much less? And how can this situation be improved?
Hopefully at least in the EU someone will wake up and make better laws or even start applying them to the current situation.
