That's a nice one-sided way of characterizing everybody else save yoursleves( or what ever group whose opinion you choose to champion ).

Good engineering design is not defeated by publishing specifications when asked. It has absolutely no influence on the design process if the answer is an honest measurement of the device in question.

If the answer sucks, and makes one's product line look 2nd rate is another story entirely. Leaving the question un-answered does leave the impression...

It is best to assume that the customer designing a circuit knows enough to look at a given product and make up his own mind. The idea that magnetics are sooooo mystical that only a designer with Xx years experience could possibly know what will sound good in a new circuit makes me laugh every time....oh well, good thing it( design) isn't really complicated.

Getting a straight answer OTOH...
