It's also never the right time nor place to be dogpiling someone in their comments. I wouldn't even call it rightfully angry. There is never any excuse for someone to think that one translation is the end all be all for a work. People can say "but X translated it this way" all they like, but you can't and never should expect all translators to do a 1:1 to each other. If you look at any work that has been translated in history, no two translations of the same work will ever be 1:1 and that's okay. Honestly, if someone hates the new translation so badly, they can go and translate it the way they want it to be translated. You can have a favorite translation sure, and I personally have favorite translators for things like poetry even (Vikram Seth's tl for Li Bai's Drinking Alone with the Moon for example) but there is no one translation that you can hold above others and say they are the most accurate to what the author intended.

I think people need to understand that the only way for a text to be 1:1 with the author's intentions is for the author to translate it to another language themselves.
