The biggest issue is that I've experienced some of that creep with GitHub Actions. It's a mess, doesn't do what it needs to do and besides "presenting" features/functionality it can't actually do even the basic things a nasty old Jenkins installation in an AWS ASG does.

They practically just copied some Azure CI stuff over (which was obviously written from a completely different perspective/mindset) using a tech stack that is old yet immature when compared to even relatively young products like GitLab CI.

If a company wants to come up with a CI product but can't even get on par with basic nominal GitLab CI features and usability, what's the point...
