There's probably an argument there about looking for original marketing approaches, as booth babes are an old and one "might" say overdone idea.
but meh, bring on the booth babes.
This is true whether or not you "fall for" the BBs.
Is it possible that you'd be letting your bias get in the way of your business sense? What if those products could have significantly helped your business?
If women with tight clothing are the best reason you can think of to not purchase a product, that is a pretty damned good endorsement of that product... Your objectivity is compromised if that is how you make your decisions.
If women with tight clothing are the best way you can think of to sell your product, that's pretty telling of the technical merits of your product. It's safe to assume you've given up at that point, and you don't have anything else worthwhile to see.
If you are making your purchasing decisions based on the presence of women in tight clothing instead of the absence of technical merits, you are compromised. You should be able to judge the technical merits while ignoring the "booth babes", otherwise you're not much better than people who only purchase products because of them.
If no technical merits are present, then you by certainly have a far better reason to not purchase a product than just "they had women in tight clothing".
I find your nonchalant suggestion sell out morally on this topic appalling, particularly as a woman myself.
Business should not preempt ethics.
