If you understand linux it’s only a small leap to understand selfhosting. If you understand selfhosting it’s only a small jump to hosting your own Fediverse instances, thereby completely eliminating your dependency on the big social media giants.
Anecdote for support:
In only two days I went from “I can use BASH and the GNU Coreutils for most of my daily tasks on my PC” to “I understand networking well enough, own a domain with several webapps, and have successfully gained independence from the tech giants regarding cloud storage.”
In two days, with only the purchase of a domain for about $10US, I’ve saved myself $15/mo from spotify, and over $40 from all the video streaming apps by rolling out Jellyfin, as well as Regained ownership of my photos from Google by downloading everything as a zip and rehosting it on my selfhosted immich instance.
This stuff is genuinely not difficult, it’s tedious for sure, and for an OSS noob it will take some time, certainly more than it took me.
Every normie doesn’t need to spin up an instance to hurt meta, just enough of them that migration becomes noticeable
