Embargoes allow real journalists to do better research, to make sure they understand what they are writing about and to, in general, provide higher quality information than TC would ever consider doing.
That's true, but basically irrelevant because "real journalists" (by that definition) are only slightly more common than unicorns.
And it's irrelevant even wrt real journalists because the significant value that they actually add is their "scoop". If readers don't care, if they're satisfied with the reprinted press-release, ....
Anyway, TC is not journalism, it's a blog.
