Sure, but as a corporate executive you also have a limited amount of time. If you invest all of your time on inefficient sales processes then you may only get to consider one or two or three providers. If instead you eliminate the ones that have bad signs (like heavy price obfuscation) you can instead focus on the vendors that don't do those things. In the end you might not get the best product and/or the best price, but the same is also true if you waste all your time jumping through sales hoops and aren't able to examine more players.

If jumping the hoops guaranteed the best price, then I would agree with you, but I would vehemently disagree that it does.
