As a corporate executive, buying things for good prices is a substantial part of your job. You're not some grandma looking for a movie to watch who will bail if she can't figure out how much it costs. Sure, you can refuse to buy things altogether, but it won't be very good for your company - these kinds of companies seem to have been broadly outcompeted by ones that do buy things.

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.
