To be more mainstream granted it isn’t because of a shitty locked down distro incompatible with the others.
What I love most abou Linux is its freedom. It doesn’t try screwing me over for their own benefit, gives me full control of the system and is broken down into components. Having the underlying system foss for many is great to provide and make it easier to adopt more ethical software for computing.
Yes for all except youtube. I use frontends there. LBRY when feasible and there’s not a lot of content creators on PeerTube at least we got “The Linux Experiment”. PeerTube needs a monetization model imo (benefiting content creators and instance hosters). I wouldn’t mind paying a low fee for watching content for instance.
