FWIW I don't think these voluntary commitments are sufficient or address all of the important harms. But that's different than saying any government action is just "regulatory capture" and an attempt to keep open source models down. I'm only attempting to argue against the latter here, which I'm not sure is where you're coming from.
Not particularly without barriers to competition in the space being artificially erected so as to enable that, which is the whole point of the industry-government game of footsie.
No, I think wealthy and capital rich companies can leverage AI to extract value from places that already extract value simply by underpaying people and use stupid rhetoric and other methods that they are very familiar with to continue buying up basically everything as most normal people struggle to survive.
I explicitly do not think "AI" or even AGI has any inherent danger in itself, and only has danger in the same way any automation has in a capitalist system that also gives richer people more power in the justice system and the political system: Rich will get richer by squeezing the non-rich even harder, while politicians don't care because most of them genuinely believe in capitalism as an unabashed and incorruptible good and the misinformation and discourse control that passable bullshit generated with a single keystroke grants them way more power
