> It’s one bug.

It's a security bug that leaks information about the user. It reduces privacy for the user to any website they visit. Chrome and Firefox fix these security bugs immediately upon learning about them. Safari does not because it had hyped ITP and is more interested in security theater, which makes for great marketing, than actual security.

I don't know why you are trying to redirect the conversation to services that can be accessed from any browser. The topic of discussion is which browsers are more secure and offer better privacy.
