I just dug around in the rush GitHub, and was surprised to find no pull requests by the author of Lerna trying to rectify the missing copyright ("Hey guys, you forgot to keep my copyright in there since this is a fork of Lerna, so here's a pull request"), or any issues raised ("The copyright of my MIT-licensed project is missing. What's up with that?").<p>The only instances of lerna being mentioned are people who use or work on rush mentioning differences between the two projects.<p>Assuming the lerna author is accurate, why just the angry blog post? If I had contacted MS and raised the issue via email, and nothing happened, I would have started raising issues on the project GitHub and making pull requests to rectify the situation. Not only could that actually work to resolve the issue, but the discussion would be public.
