Is it just up-front cost? I understand that for larger instances because they’d have to setup heftier systems, but even micro-instances seem to rent cloud compute when they could probably get by with port-forwarding to an old laptop.
Edit: I understand that self-hosting is a skill that takes years to learn, and I’m aware that the vast majority of people on Earth choose to spend their time and energy investing into completely different topics. However, Lemmy tends to attract the techy type, so I suppose I just assumed the ratio of self-hosters-to-not would be higher. I’m not saying it’s trivial, just that I presume more Lemmings know how to do it than, say, Redditors (taking total users into account ofc)
Specifically for Piefed/Lemmy, I have all the experience and knowledge necessary to self host my own instance. I’ve been managing servers since before half of Lemmy’s population was born. And what it has taught me, is it is always better when its is someone else’s problem. My home lemmy instance closed down, which could have been a chance for me to self host, but I, instead, spent a little time finding another instance I liked, because I didn’t want to be responsible for it.
I actually own a domain with the idea of starting a Piefed and Mastodon instance, but I’ve never been willing to set it up and deal with the overhead. Maybe one day I’ll decide to, especially if feddit.online ever goes offline, but for now, I enjoy it being someone else’s problem.
Also, I’m pretty sure the fediverse wouldn’t work if everyone had an instance of 1. Maybe some day someone will crack a fully distributed P2P ActivityPub like solution, but until then, the health of the swarm requires we stay somewhere between “1 company runs everything” and “there are 7 billion fediverse instances”.
