The reality is if you are not concerned about trust, openness etc Chrome/Webkit is currently going to give you a better end user experience. With Mozilla losing the moral high ground, my reasons for using it over Chrome and especially Firefox OS over Android(or Firefox in Android) diminish greatly.

I think I'll choose not to use Firefox anymore. Google swiftly reversed their bad decision to include a silent binary blob downloader, but I didn't go back to Chromium because that trust was broken.

What I mean is, it's not so much about open source (I used closed source technology every day), it's about the overall openness of the project. Mozilla has chosen to integrate a proprietary service in what is supposed to be an open browser, and that bothers me enough to not use their product anymore.

And if it's not already apparent, no, I won't be using Pocket either. :)
