Bollocks. "Hype language" has a very strong correlation with people who don't know what they're talking about. (Probably because most people who use it do not, in fact, know what they're talking about, even if some might.) So other experts in the field will look down on you if you speak like a British university press release.
I agree with you. I just think it is wasted effort to complain about the quality of press releases. I am consigned to their poor quality, and my solution is to read primary sources.
