Eh, but it often boils down to someone else's enjoyment stepping on your own (either directly or indirectly) when it comes to a single company with limited resources to allocate.
In anthropology this idea is called the theory of "limited good" . . . that good things happening to others takes away from the finite pool of good things, so I get less. While there's an element of truth in it, it doesn't hold up in most circumstances.
You're assuming that if WotC decided not to make the product you like, they'd make one you'd like with those resources instead. They might, they might not. They might make another product you don't like, or nothing at all. And with things rarely being as simple as Product X substituting for Product Y, a product made that you don't care for might increase the bottom line to a point that the company can afford to make more products, maybe some you will like. And conversely, if they don't make a good product that doesn't happen to suit your tastes, they may loose money on making the thing you want. Or not.
Should WotC redirect the resources put towards Magic: The Gathering into making D&D bigger and better? If you don't play Magic and love D&D, this might sound like a great idea. But Magic is such a popular and high-selling product, chances are its loss could possibly kill the company, including D&D.
And, besides, as Scribble has pointed out, rooting for a product to fail just because you don't care for it . . . just seems mean-spirited to me.
