No offense but that's just American centrism at play. Lingua franca of computing is English, everyone should just learn "the human language" and it'll save everyone's times, computer runs in English, everything should translate clean from English, etc etc.

There's nothing wrong in using local languages. Speaking not-English is not bad. Many go for English because there's a lot of money to chase in the market, not because it's objectively right by some truth of this universe.
