The problem is that people like Trump have made an effort to reappropriate the word, so it's lost all meaning. Fake news, in it's original meaning, wasn't simply inaccurate news or biased news. The newsroom didn't make an oopsie. It's was blatantly false stuff.
Fantastic tales with no corroboration. Many of the people producing it knew exactly what they were doing. We're talking about stuff like the first lady being trans, or dispensaries taking food stamps. There's also grey area people, like Alex Jones, where it's not clear how much of his stuff he truly believes.
We don't live in a great time for the press. We just elected someone famous for pushing fake news (Obama's birth certificate). Unfortunately, Trump has been quite adept at changing the meaning of these things. Now people seem to think fake news is just "bad news".
