Mechanical Keyboards

I can kind of see why keyboard manufacturers do this with their nicer models. Another issue with shine through keycaps is that they have to be very thin for the shine through to work properly, which makes them feel cheap to enthusiasts, who usually prefer thicker, higher quality keycaps. Therefore, most enthusiasts do not care about shinethrough (and, as a result, the orientation of the LEDs) and would rather trade shinethrough compatibility for keycap profile compatibility.

On the other hand, it is still annoying. For a hobby that puts pReFeReNcE on a pedestal, it can be hard to find a perfect endgame. It's already basically impossible to find the pudding keycaps with Mac legends like you said, but it would be even more challenging to find those same keycaps in an obscure format like ISO Nordic or something. It's why so many folks in the EU use ANSI keycaps even though they're inconvenient for them to use.
