I may need/benefit from using Slack for “work stuff”.
Yeah, sucks totally, but network effect is a thing.
What is the best way to use it, on Android and on Linux, from people that use it often.
Do they have a webapp? How do they do their servers, is it centralized? Any wrappers for anything I should think of?
Using it in the work profile (GrapheneOS), getting the APK from APKpure is the option I would consider as last resort.
Proprietary Android apps are incredibly bloated nowadays. Like 400MB for a random single purpose app.
I dont trust them a single bit.
All android apps can communicate with each other via IPC, if both apps agree to it. This risk accumulates the more proprietary garbage you have on your phone.
