Switch what? AFAIK it was never the intention to make the core apps open. I'm not allergic to closed source software. I'd like to see the option to swap the closed bits of software (or any bit, for that matter) for alternatives. That's freedom. But closed source is fine with me, if it provides a good UX.

Firefox and Ubuntu might be fully open, and I do prefer that (typing this on Firefox on Kubuntu), but I don't think Firefox will provide a very good UX nor high-end platform like Harmattan and Sailfish; webtech is just too limited for that. Ubuntu might do well though, given that they use a very similar platform as Sailfish/Harmattan.

I am allergic to closed protocols though.
