There will always be an open source version of GitLab, more than 1000 people contributed and it the most popular self-hosted option, used on-premises by more than 100,000 organizations. They will keep going with the open source version, with our without GitLab Inc.
But the MySQL purchase by Sun and Oracle has shown what can happen to projects when the company is acquired. The best option we saw is to at least codify our promise to the rest of the community in https://about.gitlab.com/about/#stewardship
When we break our promise it is time to fork.
Any suggestions are appreciated.
