It depends:

- what are they doing with that information
- what is the extent of your personal extremism on the issue

In Jolla's privacy policy it is stated that the information is used mainly to improve Jolla's services, which at least considering the amount of often-not-so-constructive criticism should not be something to be despised. But if your take is that absolutely nothing should be collected and they should only have that often-not-so-constructive criticism as a source of information to improve things just because collecting information is plain wrong per se like it's all black & white, then I'd say you are being extreme. But of course, why make things difficult if with small effort they can be made impossible....
