Actually, I've been seeing problems with recent cherry more and more often, especially stuff like non-clicking blues. It's because of the upswell of demand, which is still occurring.
Kailh switches are in the same style of cherry, and with the same pinout, but they aren't copies as much as any of the noname switches that are also cherry style. They're doing their own thing, and are clearly labeling all their stuff. It's in the same sport as calling Matias switches clones, and therefore worse, than Alps; but the biggest difference here is that Alps is dead and cherry is not.
I don't have any numbers on sales, but the only fair way to do measurements would be of cherry switches since the new gen of Kailh - to be defined as when the Razor switches came out - against said generation of Kailh. Allowing vintage blues or whites or anything else in doesn't make sense.
