Just hope most go to a common place which appears it will be GitLab
You know that Gitlab is also VC backed, right? They have to exit in the same way as Github did. It’s baked into their DNA. The only question now is who buys them. What will you do if that’s Oracle?
that doesn't matter much, as the platform is only one side, while the hosting/service angle is the other. ultimately, hosting your code yourself is the only safe option, but of course it comes with its own downsides.
Just hope most go to a common place which appears it will be GitLab.
