If browser migration stopped the majority from changing, Internet Explorer would still dominate. But Firefox got the majority, and then Chrome. It's a bit more fluid than the OS market. A company can't get away with just anything forever in the browser space. At least not so far. 2-5% loss is significant for one change, and denotes a chink in the armor of dominance that other players can begin to exploit; whatever dissatisfaction caused people to migrate, other players can be very good at it, which can get more people trying the other product, which if it does well in other ways, can spread. So 2-5% loss has a small chance of turning into a long, slow landslide of market share loss.= Definitely dangerous to start throwing customer experience under the bus for short to mid-term gains without paying attention to the long term picture.
