Shrug. If I had to go back to desktop Linux, and I could pay to have Preview, Safari, Terminal(! yep, I like it better than my Linux options), Digital Color Meter, Apple's office-alike suite, Notes, and various other first-party Mac apps, on Linux, I'd absolutely click the "buy" button. And I spent 20 years on Windows and Linux before seriously giving Mac a shot, and still regularly use both for various reasons, so it's not that I don't know what else is out there—Apple's first-party apps are my favorites in their categories more often than not (big, glaring exception for Xcode, hahaha). They're mostly really good, stable, and don't eat my battery like it's free.
