which is exactly what a business should do.

it's not like Nvidia doesn't invest a ton into R&D, but hey, they have the cash, why not use it? like a good business.

In a normal world, this is where Nvidia gets trust busted. But that's long behind us now.

What a business should do, sure. Businesses should - and do - do a lot of really shitty things because it benefits them but harms a lot of other things. I don't feel that it's a good justification to argue this way though.

In this case, removing a competitor, absorbing their IP, and maintain their ability to dictate the direction of an entire industry. They're hurting the industry itself by removing competition, since competition is good for consumers and also good for progression forward.

Businesses with a monopoly of some sort often stop innovating in the space and end up slowing the entire thing down. Often, they do their best to block anything and anyone that tries to do better, and effectively keep progress back in doing so, simply to maintain their position.

They're selfish self-preserving entities often driven by the same kinds of people, disregarding the harm they do in the name of profits and shareholder "value". Sure, until someone disrupts that (or they get bought out and dissolved).
