I wasn't saying that. I was just pointing out why this might be a miscommunication of good intent rather than a malicious statement, which is the subtext of the title of the post and the accusation in the actual tweet.

I personally think that, since English is an international language, Western native English speakers (myself included) should learn to forgive a certain degree of linguistic foreignness when talking to English speakers in general. Many English speakers have a perfectly good grasp of English for professional work, including support problem solving, so they are fluent enough to be competent and polite even if they might miss social nuances in casual or personal settings.

why bother? I suspect that the vast majority of the time the non-native speaker muddles through and in the rare cases (like this one) where it becomes a "viral problem" the higher-ups can sprinkle some goodies on people to make the problem go away.

I imagine their current arrangement is cheaper than paying highly fluent English speakers in the first place.
