Google does the same and their phones seems to be selling quite well.
And Apple too.
But we have 2 alternatives now (and they are even open-source!):
1. Ubuntu: http://www.ubuntu.com/phone
2. FirefoxOS: http://www.mozilla.org/en-US/firefox/os/
So why does it look like everyone's already back to "whatever!"-mode as far as your right to privacy is concerned?
3. Jolla http://jolla.com/
where (at least an earlier version of) the OS was actually shipped on a decent phone, the – Nokia – N9.
Everything you need already works just fine (and perfection will be there very soon).
