This is the first time I’m exploring this, but I think you’re wrong.
On Mastodon you can:
- Control who’s following you (also block)
- Set your post to appear only to your followers (link)
So post visibility is not something you set per profile, but per post. But you have an effective tool to decide who you let in AND remove on the way.
As others already stated there are solutions already to pin apps and to be honest, I feel I would not give the phone to a policeman like that.
On the other hand, what I’m more concerned about is giving the access to my phone’s data through different permissions to my government.
For example this is the list of permissions for the Hungarian government app: https://reports.exodus-privacy.eu.org/en/reports/hu.gov.dap.app/latest/#trackers
