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.
Well I think that’s part of the point of the Fediverse: No single server has to scale that much. Sure, the big ones are going to get big and stay big, but no one Lemmy server is ever going to have as many people using it as Reddit does. That means the cost of each instance is going to be tiny in comparison to what Reddit spends to keep one big monolithic site running (which is easily in the millions). Fediverse will distribute users across many instances/platforms which also distributes the cost. Not only do users have many Lemmy instances, they’ve also got kbin, and mastodon, plus any other platform that joins ActivityPub.
Reddit/Facebook style monolithic sites are not viable. You see time and time again these platforms desperately trying to monetize because it’s so expensive to run. Fediverse can have millions and millions of users, but no single entity will have to foot that bill.
So many new users completely missing the point of the Fediverse. We want to avoid having one big instance with one person in control. At that point you may as well name them the CEO.
