Agreed, if there was something actually better to switch to then I'd be interested. But seems unlikely for that to happen now - it's easier than ever to build a new github, at least the app itself but i doubt someone's gonna bother with the business effort needed to actually build it up as a reliable, trustworthy option that you know will be around for a while, which is a process that takes years when you know you're going to get disrupted. It would probably have to be open source to get early adopters to use it but somehow be nicer to use than GitHub, and there's basically no money to be made
