Earlier quoted context omitted.
You are mistaken if you think companies will allow common people to ignore copyright on their IP. The only IP that will be allowed to be stolen is that of other common people.
I agree with you when you talk about places where companies can bully people just by threatening to sue them, and where the defender must have lots of money even if they are clearly in the right. But AI does not change anything there. The problem of being sued into oblivion despite being right exists there even without it. In places where defending does not cost money, this works out in favor of the individuals.
Right now, we have FOSS organizations that will help you in lawsuits against companies that don't follow licenses. With "AI" in the picture, companies can launder your code with "plausible" deniability. [1]
