IMO this was predictable and I recall walking a few people in the industry through the argument and suggesting they maintain a path to migrate off GitHub for when it finally gets re-orged.

Whenever someone makes a promise that a subsidiary or product will remain unchanged (typically because that's how customers/users prefer it), it's useful to ask whether that promise has any legal force that will prevent the company from reneging on the promise if organizational or market circumstances change.

There is almost never a barrier to having the organization change their mind, which means that the promise is at best a soft promise that in the near term they don't intend to change too much too quickly.
