I'm kind of impressed that their PR guys are so incompetent. Their statement is so nakedly condescending, they might as well have straight-up said, "You guys are full of shit, but we'll stop just so you'll shut up about it."
You probably should blame legal, not PR.
In fact, they seem to agree. I loaded the page just now, and "We have thoroughly investigated this technology and do not find any evidence to substantiate security concerns." is no longer present in their statement.
Their statement is still unbelievably condescending and awful (and none of that has any legal bearing that I can see) but they at least removed the part where they outright denied any security problem.
