Before you ask, I'm typing this from my MacBook. Yes, it's painful. The sharp edges on the notebooks don't help either.
I have been disabled by RSI for several years, and now I'm recovered, I won't use anything but these mac keyboards. They are much healthier for your hands - it's that very 'tactile travel' that does much of the damage.

Rather than urging him to conform his body to the uncomfortable keyboard, how about recommending a keyboard designed to be comfortable to him?

Linked post is quite weak on evidence and is mostly filled with "I think so"-s.
I think this is very hard to research because it need a long time and people often change habits in that time.
that said, I hate apple keyboards. If there was a macbook air with a thinkpad keyboard (including trackpoint), replaceable accu and better linux support i'd pay 3k€ for that.
Laptop keyboards are pretty much universally terrible, but my MBP is probably the least. That said, my daily worker is a variable-weight Topre 103UB and it's been pretty good despite missing an extra windows key to remap.
Take some sand paper to the sharp edges. Don't be afraid. You own the machine!
To each their own, I guess. I can't use long-travel keyboards anymore since it's too fatiguing for me.
So every time someone gets one of these laptops, they need to google how to type the pound sign. How is that good design?
On North American English MBPs, the # is shift-3, just like every other keyboard here.
