But you’re skipping the very issue of this mindset. Being smarter along a very specific scale of evaluation doesn’t make one de facto « smarter » in general, neither properly adjusted to work and collaborate in an organisation.
Denouncing arrogance might not be the best move in some context, but it is not a show of weakness.

Why should people refrain from stating what they see? It's his blog, why should he refrain to express himself? Why should you decide in his stead, what does matter or not to him to express?
A minor signal is still a signal, that may, or may not, accrue to other converging ones.
