The 'results' are more plain to see in callout culture, but the negative effects are usually systematic and hidden.
In entertainment - we don't see all the scripts that were given a pass, the actors that were not considered because they were going to cause controversy by being the wrong ethnicity/gender, comedy writing rooms in particular are generally 'anything can be said unsafe spaces', which is an important part of the culture of good writing that has a questionable future.
If you go and have a look at films made just between 2000-2015 - you can see how many of them - even though they don't rise to the level of controversy today, and are probably not inherently controversial - would not get made today.
'The Last Samurai' with Tom Cruise - some could argue it's 'appropriation' I think many would argue that it's not, it's not really a 'White Saviour' film either. Though it shouldn't be objectively controversial per say, though maybe fodder for discussion, it probably would not get made because it just has the potentiality for ruin: there is just far, far too much risk in an escalating cascade of populist voices calling the film all sorts of things with or without legitimate grievance it won't matter - the mob rules.
Tom Cruise has 10 projects on the drawing board, and he's getting pitches daily, so there's going to be 'a different film' without the risk profile to his personal brand.
Studios (and BigCos) are risk averse and so what we see is a 'watering down' effect across the board.
Conan O'Brien had Sean Penn as a guest on his podcast and has some thoughtful things to say about it.
So does the analogy hold for capitalist control of Open AI? Possibly.
MSFT might be able to push for some 'results' which are seemingly more obvious and public, but the systematic effect of 'closed' and 'proprietary' results in stifled innovation and opportunity otherwise.
It's actually an interesting analogy but I think it's probably good for maybe reasons you might not suspect, and that is, the big part of the iceberg that never gets seen.
