The fact that "no one bats an eye" doesn't mean they're not internally annoyed by the key sounds. In my office, there was this person who used a cheap noisy keyboard. It bothered us, for sure, but we didn't bring it up to his attention.
Yeah, like, I'm not going to ask anyone to use a different keyboard. I'm an adult, I can deal with it.
But I do think mechanical keyboards are way too loud, way overpriced, and way overhyped. (But that's just my opinion. I'm sure people would say the same thing about some of the stupid stuff that I'm into.)
