You're insinuating there are groups inside major companies setup with the express purpose of discovering and releasing exploits against competitive products?
Since plenty of companies do this, I'm sure it would be easy for you to show evidence of a few examples.
Since the comment to which you're replying uses the word "insinuating" I deduce that originally it said "asserting" but after your comment it was edited by staunch without a note to say so. Yes?
