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.
