And yes there are also ways to stop data collection if you're concerned about giving that to them.
What makes you think the crack you apply to your official ISO isn't compromising your OS?

If you're going to install steam on your PC, then you'd be giving an attacker access to your steam account and if you ever install or use a platform that doesn't already have your credit card info stored then the attacker gets your credit card data.

This isn't true. There is no way to stop windows from collecting data. No version of windows is capable of disabling all data collection, and there's no setting you can configure that can't be undone by MS at any time, and without any notice at all to you.
At best, you can install a copy of windows on a machine that is left offline 100% of the time, but i think most gamers would find that unacceptable since even if you don't care about MMOs or multiplayer, steam is still pretty popular.
I don't object to the idea of pirating software you don't like, don't want, but feel "forced" to use, but the idea that there are no real risks to your security or your privacy by doing it is just plain wrong.
Just use linux. It can play plenty of games.
