That seems almost exactly what the sudoers file is meant for.
If several actions have to happen at once (call the phone first), or need parameters, or need a kill switch, that is what a script with the SETUID bit does.
Fix the input not the algorithm - either disable watch history, or clear it of anyone who you don't trust their viewers to recommend positive channels.

Possibly also people coming here with the kind of hateful content that was acceptable on Reddit and getting downvoted & blocked/banned almost immediately
After choosing, it's just "sign up, install one of the apps and sign in again, start reading or subscribing" - so not a world of difference from someone who has just that e.g. Threads or Reddit or a certain discord is 'their community'?

Like the coffee grinder which beeps to let you know that the [rather loud] grinding process has finished!
