What you’re describing are literally the most horrible keyboards I have the displeasure to use. For example: the IBM Model M is one of the single worst typing

  The IBM Model M is a great typing keyboard after you get used to it, but you are right that it is on the stiffer side. The previous Model F keyboards took about 10 grams less to actuate, and are widely preferred. I find even those a bit stiffer than my taste. Neither of those keyboards has my preferred feedback or force curve, though I don't mind typing on them. The biggest objection I've ever heard to either is the noise. In any event, actuation force is an orthogonal concern to travel distance, tactile feedback, post-actuation force curve, upstroke bounce, keycap shape, etc. Relatively fewer people typing on a such IBM keyboards got RSI compared to other keyboards, because the extreme tactile snap makes it very obviously unnecessary to type with much force more than barely required to actuate them. But the cause of RSI is largely down to posture and typing style more than keyswitch design, though the latter can contribute (the worst are cheap rubber dome boards from the 90s-2000s, which often force a hard smashing typing style). We would have much less RSI if computer users kept their wrists straighter, pulled the keyboard closer, tilted it parallel to their forearms, and stopped slouching as much.
