I'm a nobody, but let me answer these questions in 60 seconds.
1: None, no anonymous accounts allowed. 2: None. Civil what?. 3: It's the Google's company policy, don't use our products if you don't agree to it. 4: If devs write apps for this nearly impossible to develop Mac AppStore ecosystem, I don't see even a slightest problem here. 5: Just change package IDs.
Thank you for listening, see you again next time.
