Supporting free private repos for GitHub is not a big deal.
Revenue of GitHub:
- 50% Enterprise/Business
- 38% Organisations
- 12% Personal/Individual projects
A lot of personal projects from BitBucket and GitLab are going to migrate to GitHub! But in my company, we're sticking with GitLab.
Since GitHub only provides free private repos to individuals, not organisations (also the 'max 3 contributors')
