Because anti-IE? I doubt it was the driving motive for much people. People usually switch to something because it's better or at least because it's cool and popular.
I switched to Opera because it was so much better than anything in 2000. Then I tried Firefox because a friend switched to it and I sticked with it occasionally as it was becoming better and better and cool extensions emerged. Then I switched to Chrome because Firefox became so slow it was driving me crazy (yes, I always use obsolete hardware) and Chrome was ok (it lacked functionality I loved in Firefox extensions but I could tolerate this).
Now I actually am increasingly anti-Chrome because I don't want Google's monopolism and dictate so I feel like I want to switch back to Firefox and guide friends to do so but Firefox is still notably more slow than Chrome although not as slow as it used to be. I hope Mozilla guys are going to keep on improving its performance.
