Besides that you can still use a desktop PC. Most people do anyway.
I'm have very negative outlook on Apple with their vendor lock-in and walled garden, but how long do you think Google will let you make this choice if they gonna have no competition at all?
Google was slowly making Android less and less open with every release. Now "security" features like SafetyNet decide whatever you're allowed to use software or not.
Think on it! Just look at what Google doing with web because of their monopoly on search and browser markets.
Google might have a monopoly on the web, but at least they have given us tools to work around it, unlike Apple.
No you don't. Much of the software preinstalled on an Android device is permanent. And you can try stripping out Google Play Services, but good luck having a "smart" phone.
