Even in the past a lot of “aristocrats” had to earn a living. Among scholars, many worked as teachers or had sinecures that paid the bills, or held clergy posts with minimal responsibilities.

Aristocrats were a dime a dozen.

What do you mean?

In any case mathematics is humanity's oldest open source project going on for millenia, it never belonged to a single country, institution or class.

Your local trailer park was never going to be able to afford sponsoring high energy particle physics experiments projects that hollow out a mountain and use up a ton of xenon to try to detect a stray particle. High end science has required deep pockets for a long time.

But given the cost of a college textbook this is a pretty silly complaint to lobby against a subscription that's $200 a month, in the context of the cost of a variety of other materials and tools out there. (If you think that's expensive you've clearly been lucky enough to never have to deal with commercial software costs) Also not sure how quickly this stuff uses up limits; $100 or even $20 subs might be enough for students. And if a student is scrappy and figures out that Luna can meet their needs then I'd imagine Luna is effectively unlimited on some of these subs. Luna Max scores pretty high.
