Its good for the buyers, and good for broader society and the economy.
Its bad for vendors.
Why would vendors do something that is bad for them? HN is full for people talking about how to create a "moat" for their products. Why do you expect hardware vendors not to want to do the same?

of course they want the moat - the point is that society as a whole should force them not to have a moat. Ala, they should not be allowed monopolies.
Unfortunately, this sort of legislation has been lacking recently, and in fact, has been failing even enforcing existing ones from yester-century.
