I think the core team is talking in a ‘rude’/‘direct’ fashion, which sometime make people uncomfortable. This style is quite different from other tech communities. I don’t think core team are bad people and actually they are great, but the ‘communication style’ will never get mainstream.
Straight to the point, can talk more in depth are the good side of this style.
Most of the people get bad feeling and many topics would be dismissed from the beginning are the flip side of this style.
