I also did. I got sick of not owning my own computer and phone anymore. And also the locked-down nature. Every release they change stuff that I sometimes don't like and there's no options to switch things. Opinionated design. I was pretty aligned with apple's vision in macOS tiger but around Maverick/Sierra things started getting too misaligned with my own needs.

I'm so happy I moved to KDE which has options for everything. It was a breath of fresh air when I moved and it still is, every day.
