No, I'm fairly certain I refuted it.

The parent comment is incorrectly stating that each request to Apple is checking a binary, and it's not. This has been well documented both here on HN and across the web.

That's not the definition of refute. The distinction between a lazy-implied always and merely often is pedantic. The point is that it happens enough to reduce performance, while doing something no end-user asked for and is difficult, if not impossible to disable without reducing other security protections.

There is no measurable performance loss from that one time check - it's not something happening constantly.
