If users have to agree to every bullshit license terms then I'm sure companies can do so too when it comes to some open source license that would give them legal liabilities over those who breach those terms. This is not unfeasible at all, just has to be done on a legislative level that would enforces it. The EU has done quite a few regulations for the consumer so I don't think it is out of question. But I do think it is unlikely because video games are like an enigma to most politicians and still kinda stigmatized within older generations especially.
