I don't read it as legit critics. It's OK what some projects have core team members coming from different cultures. I find it fascinating and think we should embrace that.
On the other hand, it could be read as something between the lines: "the project actually is not community driven/owned and all the code must get accepted by single person. and you see some personal difficulties there, just because of language/culture barrier".. In that case, yeah, I see your point.
