Can you point me at any data which supports this? It seems like it should be true, but GHC didn't appear to see a year-over-year increase to contributors when they switched from Phabricator to GitLab in December 2018.

I added another comment to https://news.ycombinator.com/item?id=23686803 about case studies we hope to do about this. So while we don't have any to point you to today, we hope to have some in the near future.

Another thing that we hear from people considering a move to GitLab is that they really like how fast GitLab moves (one release per month!), and how it works with the community to keep improving the product. I recently joined as the Sr. Open Source Program Manager as part of the Community Relations team, and we're thinking a lot about how to continue to improve the experience for our community.
