Earlier quoted context omitted.
Your work just sounds very subpar. Crippling developers with that sort of equipment and environment is a poor move and also an awful trade-off, business-wise.
I have to say employees are just as silly sometimes. All my life I've always just bought the stuff I need and took it to work. No matter where I've worked it was 1/100th the hassle to do that rather than figure out how to go through channels. I've also tried stuff and ditched it a few weeks later and tried something else. this applies to lots of things at work -- who cares if the office pens are free - they suck.
If you want to employ me, please provide me with the tools to do the job properly. An ergonomic keyboard, mouse, chair and desk are a given. A nice display is a bonus.
Especially when it comes to ergonomics I don’t understand employers, an engineer going on leave for a week because of RSI / back pains, is way more expensive.
