In my rebellious journey against the US oligarchs, Zuck (Facebook) and Bezos (Amazon), I have managed to find alternatives to:

Facebook with Friendica
Twitter with Mastodon
Amazon Music with Qobuz
Spotify (who have donated £150,000 to the orange man who should not be named) with Qobuz

I can confirm that there are very good alternatives and, they are better, because they don't have ads and have better ethos. My journey was interesting and not complicated.

Qobuz has even automatically downloaded my playlists. Impressive.
