Good luck trying to enforce trademark law for namespace on a public code repository.

It’s “classic trademark stuff” insofar that people classically don’t understand what a trademark is or how it’s enforced.

Consider reading through Github’s policy on trademarks[0] to better understand why a casual fuck off should be given whenever you get misleading, threatening emails.
