Look at this from anither angle: on MacOS it is worse. You can "buy" certificates/approval only from Apple. If Apple doesn't like you, you are screwed!
I'm not aware of any situations where Apple has declined to offer a developer certificate to a developer, outside of situations where they are legally barred from doing so (e.g, for developers in countries subject to US economic sanctions, who would probably be unable to obtain a software signing certificate either).
