Why do news articles quote Twitter and then reprint what they just quoted?

I need a cite on this, because it is absolutely contrary to copyright law.

If Twitter had a problem with people embedding tweets on their own pages, then they would stop doing it. The embedding only works because Twitter has specifically set up their system to enable it.

Something got crossed here. The only problem with it as far as they’re concerned is that it costs them money–a cost they have decided to absorb, anticipating income as a result.

Cite from Twitter’s TOS:

In other words, no, your tweets don’t belong to Twitter. They just have a non-exclusive license to use them.

Yes, their license is essentially identical to the Dope’s.

Or, I expect, to pretty much everyone else on the Internet that has user-submitted content.
