I'll admit that I don't actively seek out Poettering's online postings, so I pretty much only see his behavior when it's bad enough to make the news. But isn't it a little silly to say he's generally polite and helpful in most of his interactions? What really matters is whether he's capable of being polite and helpful when there's a real disagreement, and especially when he's wrong. His reputation indicates he tends to have a distinctly impolite "my way or the highway" attitude in those circumstances, and examples of it are plentiful. Are there counterexamples where he humbly admits being wrong, or at least acknowledges the validity of criticism when affirming his stance?
