What constitutes Usage Data. Is it sharing the posts I view, communities I subscribe to etc?
Does paying for a premium version stop this data being collected?
I believe its possible, at least coming from the minecraft world. if the instance doesnt grow as big as lemmy.world or something then you can ask for patrons and other ways to get donations. a lot of the plugins I use for my minecraft servers are run this way and its the way i run my server, I just ask for a dollar donation if possible from my players and that covers a little bit more than what the server costs me to run. when I check some of the plugin's patreon page they pull in about 1k-8k a month
