I imagine that the idea of a lie-to-children applies. Press releases, even when they're not deliberately deceptive, often simplify things to avoid the "too technical for our audience, reject" response from editors. As a result what the press release actually _says_ is often technically a lie, but the sort of person who cares would know better anyway.
Spending half the subject line explaining that your company is announcing something done by a project that is technically independent of the company, - well, that's just going to reduce the chance anybody runs the story. Also if people are picking up the story because of the words "Red Hat" (after all RH is a big tech company now like Oracle, some of the places that run this material may still feel the need for a sidebar explaining what "Linux" is whenever they mention it) then removing those key words means less coverage.
So I wouldn't be at all surprised if the Red Hat release normally says exactly what we read above.
