What a weird thing to be butthurt about. You don't have to pay them. Do it the old fashioned way, with elbow grease and pots of coffee. Or invest in local AI.

Or embrace the future and realize that you couldn't imagine everything that would unfold, when you pursued your undergrad.

How you gonna get mad about all this?

There was a time when a generation of hackers got (rightfully) worked up about the Microsoft tax for every PC sold. It's not hard to see that somebody gets mad if they believe that an Anthropic/OpenAI tax is about to become the standard when doing any serious Physics/Math/... research or writing code.
