The reason for voting this up isn't so people know that it's good to communicate well. The reason for voting this up is to correct a misperception with what was said. Corrections rarely ever get the publicity that they deserve.
The right way to have communicated would have been "Oh shit, I didn't mean it that way, sorry guys. I understand how that may have come across poorly." instead of "What me racist unpossible!"
"I'm not sure why. It could be that there are a bunch of subtle things entrepreneurs have to communicate and can't if you have a strong accent. Or, it could be that anyone with half a brain would realize you're going to be more successful if you speak idiomatic English, so they must just be clueless if they haven't gotten rid of their strong accent."
He is talking about strong accents as a superficial data point. You would have to make shit up to infer anything beyond that.
I actually think his second suggestion (a lack of a critical kind of sensibility) is the deeper and more meaningful one.
Yes - it's the type of thing you have to jump on quickly before the negative PR spirals. And unfortunately, corrections and clarifications rarely get the hype that original articles or misquotes get in the first place.
