Why bother?

Dear Internets,

Please explain to me why some people "blog" (I'm using that term very loosely right now) about events but rather than saying anything about it merely copy and paste an entire news article into their post. Or say, "OMG! Did you see this???" First off all, do they not understand copyright law? And why not just link to the darned article? And what's the freaking point?

A very frustrated,
