Seeing some of the comment here, you could make a conspiracy theory that NVidia/MS/OAI used their generative algorithm to write comment defending them on HN :p .
All jokes aside, I know that antitrust is not just about monopoly, but if we just focus on this part, it really does not matter if one company became a monopoly fair and square by just being better/smarter/luckier than everyone else, you still probably don't want it to be a monopoly. And making sure it still has competitor is usually beneficial in the long run.
A monopoly might act "fair" for a long time (although it would be hard to know since you won't have anything to compare them with), but their power allow them to turn against the consumer whenever they want with little to no consequence.
As an example, you can't really complain about an inquiry against NVidia, and then complain about their pricing and/or how hard it is to get some of their card (especially the one meant for training) because they don't care about you if you don't have a good relationship with them (and a lot of $$).
All in all, pretty sure this inquiry will lead nowhere, or just a slap on the wrist, as is usually the case. It is just a signal to those company to be careful and to avoid using their dominant position on one market to push themselves unfairly in another.
