None of the apps broken on my phone require Facebook features for core functionality. Downtime happens, but downtime due to your non-essential & user-hostile ads/tracking/social SDK? These companies deserve every single cent of lost revenue.
If the last time this happens is anything to go by, a lot of apps have the FBSDK to facilitate their "Log In
with Facebook" functionality. The issue is that you have to include a monolithic SDK that initialises itself without your control just for simple functionality like that.
Temporary workaround for people who need Spotify as badly as they need oxygen (Eg: me, and my kids)...
Turn airplane mode on, open Spotify, go to Settings > Playback, set it to Offline, then turn airplane mode off.
At least now you can listen to cached music and browse the web again.
Longer term, install a Pi-Hole on your home network and block all Facebook owned domains, because they’re a scourge on humanity and your life will be much better void of their infection.
How is this even possible, even less acceptable from Spotify point of view?
