Maybe, thinking this as a non-English native speaker, most of the Internet is written in a foreign language, so we are used to adapt ourselves. We don't expect to have everything available in our language. Heck, I'm really used to google "einstein en.wikipedia" for example, as I assume that the english article will be much richer than in my own language.

But when most of the world speaks your language, it looks like some people (I'm not generalizing here) are so used to expect english versions by default... that using tools like this feels bad.

Maybe some day, as our tools get better and better, this can be a thing of the past. Until then, if I can understand most of the text, it's not that bad.
