I have listed several reasons why I think so in other threads here already, but the main thing is that what I longed for in 2008 when I was getting my first smartphone was a connected personal computer that I can put into my pocket and carry around through a day, and that's what I was always getting with GNU/Linux phones, so I never really got used to the idea of smartphones as these limited, mostly vendor-controlled devices that effectively serve as a trusted runtime environment for adversarial software (and by "trusted" I mean trusted by apps, of course). Instead, I see my phone like I always saw my GNU/Linux PCs - as a tiny box full of useful tools that are there to serve and empower me to reach my goals and which I can put together and modify any way I like to. May not have the sleekest design out there, may not be a speed demon, may have a quirk or two to tolerate and may require me to scratch some itches by myself, but it does what I tell it to regardless of whether it's aligned with some corporation's interests or not and it's well worth the effort spent to configure it to my liking. It's also generally a wonderful thing to tinker with (though this mattered much more when I was still a teenager :))

It just feels like my little personal computer. No Android device ever felt this way to me. I don't want to feel like a guest confined to a sandbox within a computing device I'm supposed to own.

If what you care about is protecting device and application providers' interests from their users, then I guess it does.
