The bigger issue in the sales/developers divide is that neither of them is tasked (assessed, paid for, whatever you want to call it) to 1) understand the actual problem/feature request (before even thinking about solutions), and 2) write end user documenration and/or try to explain to explain the solution to the end user. If only sales and dev drive product direction, with neither of them having explicit focus on what the end user needs, you end up with overly complicated, half-assed products, that kind of work, but not really, and nobody wants to touch. On the other hand, what matters is money in the bank, so doing stupid shit like this is fine if the cash flow looks good.
