I bet you'll find that some do have patrons or subs or something similar.

If people want to share their work for free, that's cool. If people want to charge for their work, that's also cool.

The fact is, being good at something creative takes the same time and dedication as anything else, but because it's entertainment or art people expect it for free 'because it's a passion'.

Should doctors passionate about medicine not get paid either?

The fact is if you want a rich culture full of awesome art, the people creating that art need to be fucking paid.

I'm not necessarily in support of monetising the fediverse or anything like that, but I also don't begrudge anyone creative trying to actually get paid fairly for their work and time.

Sure, some of them are doing it for hobby, but most of professional comic artist that post freely on internet are doing patron or various monetizing way.

You must be not familiar with entire creative ecosystem.
