Would also like a write-up. People assume it's just because of GitHub outages, but GitHub is slightly worse in every aspect, so for big projects and organisations it compounds to being quite messy to manage and operate.

GitLab is thought-out to support larger groups with more complex pipelines, and while it's got it's own set of quirks, it doesn't begin to compare, GitHub in contrast seems like a toy forge for toy projects.

why? like having a dozen outages in the last couple months isn't a good enough reason why?

Roku uses Gitlab internally so could just be a standardization thing.
