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.
Honey, no… I appreciate where your head is at with this one, but the goal is to make browsing an instance a good experience, and as computationally simple as possible. Adding mining to the front end of an instance client is very poor for the long term sustainability of the app, because it will incur electricity costs for the end users that will have diminished returns for the instance. So it is a very inefficient way to fund large instances. Users would save money by giving instances money directly rather than letting them mine on their clients.
Ads work because the advertiser believes that their is market value in showing a user an ad, and they can be right or wrong, but financially they are willing to pay more than the electricity cost of showing the ad. I don’t even mind the idea of ad supported instances in principle, although I would probably block them to preserve my browsing experience.
