You seem to have this personal weird exception to the guidelines, which is "Please submit the original source... unless it's a corporate press release." ;-) But you still allow meta-links about corporate press releases, which may put the PR in larger perspective but don't otherwise clearly gratify intellectual curiosity.
I'll diss the corporate press release any day! Beyond that I'm not sure I follow your specific point. What do you think we should do differently?
The question is why HN allows a meta-link about a corporate PR (for example, a Verge story about the PR, since you don't like the direct link) but not something like this? Why is "Corporation X announces Y" intellectually interesting, but this isn't?

Don't you think that certain links can be newsworthy despite generating predictably ugly discussion threads?
It does seem that you're saying the site is not about news per se.
