I think they should help their median users and empower their power users, and they should absolutely throw a few "most vulnerable" users under the bus if that's necessary. Otherwise you think about banning kitchen knives to protect the "most vulnerable users" who are too stupid to handle a knife. No, we shouldn't do that. Their stupidity should be their problem, not our problem.

Some degree of collateral damage must be accepted to maximize the expected value of a product or service. Minimizing risks can't be the top priority. Don't ban kitchen knives. What you are effectively arguing for is transforming both Windows and macOS into a closed iOS. Don't do that.
