This isn't true at all. There's a whole world of artisans and fine artists that range from middle class to broke, and they wouldn't be in that financial situation if they felt like compromising their point of view for money.
To be more blunt, you aren't saying anything at all. You are just posturing.
If I was to be charitable, I guess maybe their argument was that Kant only believed in subjective universality because he was rich, but that doesn't make any sense. Both Kant and Hume grew up middle class, and ended up in academia, and had very different conclusions about what "taste" is.
It's just a knee jerk reaction to dead white men philosophers and anyone who is interested in them as a bunch of elitists. That's not an argument, that's some kind of misplaced class resentment masquerading as an argument.
If someone likes what you make it doesn't matter where you come from.
Taste is often advanced as this subjective yet ultimately discriminating notion which refuses to be pinned down. Insistent but ineffable. This idea that you and I know what good software is due to having paid dues and they don’t, and the truth will out, is a common one!
My argument isn’t that it’s class. It’s that this framework of describing taste is PURPOSE BUILT to ignore questions like status, access, and money in favor of standing in judgment.
Here I don’t know what the trouble is. I’m sorry for calling your phrasing the equivalent of “hafalutin” (a word Marx has used more than twice—he’s dead and white), but what do you expect having come in to cloud the waters with 2 extra syllables to little end?
