Last I checked (admittedly a couple of years ago), they also did some tracking behind the scenes, in the bit of code that they had pointedly not released. The undercurrent vibe at the time was that there was no real guarantee that they wouldn't shop around your aggregated data; all I read in that interview is that they have not been "forced" to do it yet, but hey, "life is life" kinda thing. They still do little more than throwing tarballs over the fence every once in a while, with a muddy license that follows the letter rather than the spirit of opensource. There is no real bugtracker nor transparent development practices.
I understand why they do it (people gotta eat), but to me that looks even less trustworthy than Mozilla, which at least has a certain entrenched culture that typically tries (not always successfully) to blunt the worst corporate decisions, and follows real opensource practices.
