1) Since they did not fire that founder, he retreated, 2) they broke those plugins to achieve significantly better performance, security, and an easier to work with, less often breaking extension API, 3) they need to bloat their browser to keep up with webstandards, other browser vendors are doing it just as well for the same reason and 4) is adding features that maybe you didn't ask for, but they've probably received good feedback for.
