Well, the real and underlying problem causing this is that they have the final say on what operating systems can run on iPhones. They don't do this for Macs.

Ultimately, though, someone needs to maintain a database of malware. When this malware is attacking the platform, it kinda makes sense for the platform maintainer to maintain the database. Microsoft maintains the Defender database, which does have false positives, and we thank them for it. If you want to override it, you can. Notarization works the same way on macOS.

That said, the neutrality of the database (malware only!), and the ability to override it are both key components.
