This is very obviously not an accurate description of events. In reality – author feels (rightly or wrongly) offended, submits a patch to resolve this, and in response is essentially kicked out of a core position.
That's not just 'unnecessarily rude' – it's a stupid and broken way to run a community.
That said, I fail to see why we should care
Because I think generally we want to encourage reasonably welcoming open source communities, and responses like this seem generally disproportionate.
