It probably goes against the philosophy or whatever of FOSS or Lemmy itself, but why not be a little evil so that you can actually sustain yourself? Donations can bring us far, but small non-intrusive ads can be a bliss in the skies for the people actually hosting the instance. Especially if there are millions of users uploading thousands of images and videos. This is extremely expensive.
Is running ads really that taboo?
EDIT: some people seem not to get the point of “millions of users”, which presumably includes non-techies that do not use adblockers. I mean that without ads (or mining?), no instance would be able to scale to the point where it can compete with Reddit for example. If you were to want that. And not for profit, but solely for sustainability.
I think it’s reasonable for some instances, where there’s good alignment. There was a thread I replied in a few days back around how/if TTRPG creators(who are mostly small enthusiasts themselves) could advertise in related magazines, and legitimizing that business wouldn’t really pose a conflict for the hobby - that’s how it was built in the first place! It’s just a matter of finding a place for it and defining the technical solutions.
As a general “let in all the advertisers and promise riches for someone” measure, it does cause known problems. There is some freedom to figure out what works in a specific case here, it’s not defined top-down since it isn’t centralized.
