What about Obsidian app on Android asking for permission to access all files on the device?
Did they publicly establish that that the scoped storage is hurting their performance to an unacceptable degree, before making that choice?
What if users are not fine with that choice of giving a blanket approval to a closed source system.
There is no good reason why Obsidian needs to see more than its own files and the specific documents that the user wants it to see.
Would you trade absolute dogshit performance (looong delays for syncing notes between mobile and desktop) for privacy with a product you pay actual money every month?
