That's fine for your code repository. However git has more: - Bug tickets - PR - Wiki - many projects use their githubpages as primary homepage - newly GitHub actions And then: Often collaborators are only known and identified by their GitHub handle. Running an own server requires some mechanism to identify them again and creating a way to handle their access credentials (ssh key etc.) Moving a mildly successful project isn't easy. Good if more people plan for that eventuality, even if they stay on GH for the time being.
