Truthiness and bias are different.
Also, 'editorial' vs. 'news' are actually different categories and we know what they are.
'Fox 5' - their evening show is pure gossip and innuendo - it has nothing to do with reality or the truth. Their nighthime 'personalities' are editorialists. But they do have regular news segments as well.
All of that can be categorised.
Also, the source of their bias can be roughly identified. Mostly they are a corporate entity playing to an American audience. They have some relationship with the White House on some occasions.
We can delineate.
Because it's a fairly established institution, we can also look at the other kinds of bias. And of course, each personality is different.
They are not owned and controlled by the Kremlin, or the Canadian Government as is, the CBC for example. We can delineate there.
It's really not that hard.
And FYI it's not as though there is hard censorship - you can retrieve Putins' own 'Mein Kamp-ish' rants any time with fairly easy searches.
What we don't want is bad misinformation seeping into the top of arbitrary searches etc..
If someone wants to read 'My Pillow Guy' that's fine, but his opinion on Putin is not going to come up up first when I search 'Putin', unless there's some other, factual, direct relevance.
