Fair enough (sort of), but if I were to start a business in a language that I'm not a native in, I wouldn't try supporting those people using non-native speakers. The languages and idioms of cultures differ greatly around the globe, and sometimes you may need to tweak your site to meet the expectations of your customers.

Then again, I don't run a business, so the costs of localizing customer support and "fit and finish" for Zendesk may be justified by the benefit.
