"Wait a moment. Doesn't 'nofollow' mean 'I don't vouch for this website?'"
I believe nofollow means "I am not linking SOLELY because I think this web site has AWESOME content. Instead, I am linking because of some sort of an arrangement with the website owner."
When Matt Cutts said use nofollow for sites that you can't vouch for, I don't believe he was implying ONLY use it for sites that suck.
He was saying, in my opinion, use nofollow whenever there is some sort of an arrangement between the sites.
Anyway, if a site's backlink development / page rank acquisition strategy is paying for press releases, then they probably have bigger problems to worry about. It's extremely lazy. Any of their competitors can easily replicate that same backlink acquisition strategy, and then they would be back to a level playing field.
Better page rank acquisition strategies would leverage their own key competitive advantages and core competencies.
