My issue is they did this at the expense of other, more disadvantaged groups.
I myself have been coming in and out of their space trying to job hunt.
(Turns out a common trope is people don't want to socialize with someone who "lives with their parents" or is un/under employed.)
So picture you're trying to study for OSCP, and you can't find a space that's quiet. In a library.
And what you'd think would happen is someone would go "oh, you're in IT? I know someone looking for that" and solve the issue.
And then instead, they treat it like a game -- or worse, start acting purposefully othering.
That is my core complaint -- that both those spaces and those resources in the monetary sense divert disproporionately to folks who, frankly, sometimes interact in ways that make me question why they strive so hard to interact with teenagers all day.
(Also, it was often not new users -- just bigger, more elaborate programs for the same rich kids from the suburbs who used to pay for special camps and programs... but now having them held in spaces those who couldn't afford them used to do self education.)
I hope taking the time and energy to type that out helps.
Someone else commented that the library is one of the last noncommercial spaces... I honestly don't have that impression at all. I got the sense if you're not using it to do remote work, or as a community center, but to... check out materials and use them... you are unwelcome unless you're buying stuff (coffee, supplies etc) or part of one of the groups that makes substantial donations when they're not making noise.
