A bit simplified on both parts -- a fish CAN leave too, and many do, by just ripping their mouth open to remove the hook by wriggling enough.

For people on Gitlab, your point about "downloading the code and moving on" really only applies to the simplest point of use on Gitlab. Anybody using Gitlab's CI/CD pipelines has everything in their repo(s) fully setup only for that, and not for other CI/CD offerings. Moving their stuff is often much much much more work than "just download your code", and sometimes with time/money constraints, completely infeasible in the short term.
