it's not about probability it's that you just made it up.

Valve has better, more probable sources of income, like for example, Steam?, they take a cut out of every sale of course they're swimming in enough money to fund whatever project they desire.

And I know that Google is willing to buy any data, but what for would it need PC specs? What marketable insight about a person does it provide? "ah this guy has a high end graphics card, he uh, well he could be a graphic artist but this is data from steam so he's uh probably a gamer ig"

I understand your instinct to doubt every company out there, it's a good instinct, companies are not your friends after all, but man, at least try to make your claims against those companies plausible not just possible.
