Permissive licensing can create what is effectively "software tivoization" (the restriction or dirty interpretation of distribution and modification rights of software by the inclusion of differently-licensed components).
The Bitwarden case is a good example of how much damage can be done to a brand with merely the perception of restrictive licensing. obviously, bitwarden has clarified the mess, but not before it was being called 'proprietary' by the whole oss community.
So I don't think op is referring to direct corporate takeover, but damage caused by corporate abuse of a fork.
