Since simple mobile tools will soon become a spyware and I use 3 of their apps regularly, yesterday I installed F-Droid after reading many Lemmy recommendations.
Wow, I'm pleasantly surprised.
A new app I've tested is Spotube (Spotify open source alternative; edit: apparently it uses Spotify metadata but it streams from YouTube. My bad.).
Thanks. That appears to be quite an unfortunate turn of events. I just deleted and replaced the apps w/ alternatives I already have in my personal list.
