Earlier quoted context omitted.
I recently got one and I admit it's really loud. But this shouldn't be an issue in a decent workplace. I have several guys near me who have loud voices and talk a lot. That's worse than a loud keyboard. Open office plans are the problem, not keyboards or loud people.
This is true. But, if you're in an open office, don't you think the decent thing to do is to not speak loudly (and therefore not use a loud mechanical keyboard)? There are mech keyboards with more quiet switches. At least use one of those.
No, that just shows tacit acceptance of the situation and exacerbates the problem over time. If you work in an open plan environment, the best thing to do is use the noisiest keyboard you can find, wear headphones that intentionally leak noise and listen to your music loud, do as many personal phone calls as you can from your desk, etc. And then, when people complain, point out that you didn't ask for an open plan office, and ask them to go to their manager and explain how horrible open plan is.
Worst case, you get fired. Big deal, now you have a chance to look for a place to work that isn't brain dead.
