Does that include all the pictures on there?
It can't. 60 million odd articles with pictures only taking 20GB? I doubt it. Just the text taking up so few space that I can believe.
I believe just as viable as a Raspberry Pi, but not much more.
That... Is interesting 🤔 Linux can be fun but it should foremost just be a way to run your apps, just "be an OS", nothing more. Choose some well-supported enterprise distro like Fedora or Ubuntu or whatever and just do what you do on a computer, minus customizing it.
I know that's not how addiction works, but I'm sure there is some way for you to run Linux without having addiction problems. Now you're resorting to an OS that spies on you and fills you with ads, is that really what you want?
Also I’ll be honest I have no idea what mastodon is.
Mastodon is to Twitter what Lemmy is to Reddit: a decentralized alternative built on the ActivityPub protocol for the fediverse.
Can give you some examples? That is definitely not my experience, the few subreddits I visit often only have memes every once and while and they often get removed quickly by the mods redirecting them to dedicated meme subreddits.
Newpipe or even better, LibreTube, for even more privacy (and included sponsorblock!).
