We also get a lot of "french language warriors" who call our call centers and complain about ANY mistake they can find. One that pops up frequently is if we use the incorrect punctuation mark (" as opposed to « and » for French), which happens a lot if a naïve marketing manager is copying and pasting text without regard for the format.
I'm guessing the situation is radically different in, say, Latin America. They can probably afford to use english IT terms. We can't, because it won't stop at IT.
As I said, actual text is nice to be translated, and translated right... but not the menus and stuff like that.
I am not dogmatically against using english words if they are commonly used but I am against avoiding native words becouse it sounds abit like corparate speak to me.
Do localize english text but not the digital concepts.
But then, my native language uses "mouse" (the english word as-is) for the computer peripheral, not the word we use for the mouse animal. There were some silly nationalists who wanted to translate everything, but they got laughed at so much that all such proposals died.
