Why do i feel that all these companies Yamaha, Korg, Kurzweil, Roland are still in the 20th century when it comes to open and honest communication about current and future products... ketron seems to not communicate at all, not with customers, not with dealers,

There are a few exceptions, mostly smaller companies, like lionstracs who despite their continous development problems kept communicating honestly... same goes for Varranger and Dan...

Whats keeping them from growing into modern communicating companies? Why do i keep having this feeling they have something to hide? Whats wrong with communicating openly with customers about their wishes and wants and needs?
