You know what’s also good “built in AV”? Good design with code that’s open to review. There’s not nearly as much performance cost to good security if you start from a good foundation. Saying windows is slower because it’s doing more security and more anti-virus is like saying I only run slow because I trip over my own feet. Like, no shit, but that’s no excuse.

And singing the praises of updates and rollback systems that are like a decade behind everything else and still a consistent pain point for users is a little bit of weird fanboyism too.
