Why change something that mostly works fine? I don't like to change set of known issues for a set of unknowns. Also those who want to avoid vendor lock in. Git repo might be moved around, do you like changing CI/CD scripts every time you change your git hosting service? GHA work really well for simple stuff. For more complex in a larger organization there is no clear winner.
