I agree with all this bullets and would love to add one more: the Linux user experience and community. You have to accept that your operating system will be an ongoing project in and of itself, and that the Linux community is not newbie friendly and has a lot of troubleshooting deadends.

Linux on the desktop still isn't all sunshine and rainbows. I can't imagine a phone being any better. I still had to sneakernet WiFi drivers onto a laptop with a new Linux install, this year. Same shit I was doing 15 years ago.
