Apple, who is known for being pro-privacy, makes your Mac "phone home to obtain a special boot signature, known in Apple jargon as a 'ticket'" just so it can boot after an update.[0] It's also known that macOS has checked app signatures online for over 2 years [1] in the past, not sure if it still does.
I'm happily using a MacBook nevertheless and I bet a lot of people browsing HN also do. Free software should be better than that, but we (their users) should also make their developers' lives easier. You can't expect high-quality software from mostly-volunteering engineers if they are fighting fires, and data-driven decisions if there is no data to begin with.
