I expect this will continue indefinitely until the product becomes little more than an AI training corpus and genericized trademark, similar to how our Xerox machines at work are actually made by Brother, while Xerox the actual brand has faded into obsolescence.
I will note that we don't use many of the CI/CD/issue tracking/wiki/etc. features, though both Github and Gitlab offer them. I'm sure they have their own particular quirks that may be a hassle to migrate between and have people relearn. I prefer to keep those tools separate, allowing the git repository be almost exclusively a git repository and spinning up other tools as needed.
