If they disabled installation of other browsers I'd be concerned. This way people can interact with a browser that is not commonly known and give it a try. Maybe some people like it, others will just install whatever they prefer. Firefox is coming to an end. The Mozilla mismanagement can't be continued forever, either people start supporting a new browser vendor or Chrome monoculture it will be.
