Fragmenting a browser between Official and Free editions doesn't seem to have hindered Chromium's adoption. Both that and Firefox are "free software" in the most worthlessly pedantic sense too: I can, right now, burn a whole lot of CPU compiling either in Gentoo without manually permitting a single non-free license in the config.

I count 41 packages in the distro repos that link against webkit-gtk, 75 that use qtwebengine, ~20 distinct binaries built on chromium, one that uses *dillo*. You know what's not in that list? Servo. XULRunner. Firefox. We really need an alternative but Mitchell Baker's $4 million salary sure isn't making that happen.
