No one who uses Mozilla software wants more cloud shit or online services from Mozilla.
I don't think that's unanimous. I'd like to use Firefox Relay, myself, and I'm willing to give thundermail a chance.
Used to think I'd go full Proton eventually, but leaning more towards a diverse set of service providers, nowadays. It's also my hope that these services allow Mozilla to depend less on companies like Google, and more on the users they ought to serve, which would be healthier for the org and better for users.
Apparently the dump doesn't include media, though there's ongoing discussion within wikimedia about changing that. It also seems likely to me that AI scrapers don't care about externalizing costs onto others if it might mean a competitive advantage (e.g. most recent data, not having to spend time and resources developing dedicated ingestion systems for specific sites).
I want to stress this: it's not that "tech bros" are just stupid—even though a lot of them are revoltingly unappreciative of the giants whose sholders they stand on—it's that they don't care.
