macOS is not configurable in key ways, so it isn't very usable unless you happen to find the one, unchangable macOS way to be the best. One Apple Way indeed.

It's also, fundamentally, closed. In this era of NSA wiretaps and everything else, that's just not acceptable. I have no idea what's in macOS, and I have no confidence Apple will do anything except give the NSA what it wants. With Linux, the attacks are much less obvious.
