Probably because of people like me. Had one on a few keyboards (including current Lenovo) and I was recently wondering why they still have them. I've never found one second of benefit, it just irritates me to even try it. Not that it's the right view at all. Who knows what "most people" prefer but the lack of them might indicate a general cluelessness of how to use them. It's possible other manufacturers don't add it because when they've tried it doesn't move their sales needle at all. Those who want it are particular about usage and eg just use Lenovo?
