I wonder whether this is a result of market conditions, or whether GitHub sees this is a first-to-market play of some sort, or whether it's something else. I hate to be a cynic given how much good Microsoft + GitHub have been doing lately, but what prevents this change from being rolled back?
Congrats again! I love using GitHub and look forward to many happy years shipping code on the platform.
Could be a response to GitLab, which had a similar offering for years, including unlimited free private repos.
