What Diki said in theory I can agree with.
But, from the manufacturer�s perspective, they are quite concerned with what �they� think.
The �they� in this case is not the audience. The �they� in this case is the keyboard buyer. And, if the Keyboard buyer does not feel comfortable having a certain brand displayed as part of their set-up, you could bet that the manufacturer will take that in to consideration in what they make and how they market what they make.
