I’m expecting spacex is different because we already know intuitively that launching something is expensive and we know there are only a small number of vendors with which to do so. So space launch companies probably don’t have the same issue…

If that price tag is big enough to "scare away" a customer, then that'll be true with or without the extra contact info collection and sales call(s) and email spam. Like I said: might as well not have the vendor and customer mutually waste each others' time with a bunch of sales ceremony that has no hope of actually producing a sale.
