Big Tech designed their platforms to keep you trapped.
YouTube, X, Instagram, and TikTok aren't neutral spaces. They're businesses built on capturing your attention and data. Their algorithms, notification systems, and content policies all serve one purpose: keeping you engaged on their terms. And their terms alone. There's no freedom
The selfhosting movement sets people free in general.
Does selfhosting movement include using non-commercial instances of apps like mastodon/lemmy/matrix etc?
Self hosting movement is hosting stuff yourself, so kinda, assuming you’re not putting some kind of advertising on your own services, but most commonly I’d see things like jellyfin, nextcloud, navidrome, immich and then a bunch of other stuff, there’s foss alternatives to most commercial offerings.
Awesome selfhosted
Is a great place to start.
