corporate news rarely lies outright. libel is illegal. articles will spin and speculate, emphasize and elide, omit and opine, but that's not lying, it's spin, and a careful reading can extract the facts of the matter.

yes, you have to cite reliable sources on Wikipedia. yes, this means AP is considered more reliable than someone's Substack. you can, however, cite NPR or PBS, the BBC or the Guardian. if two reliable sources differ, you cite both and describe the conflict.

how do you know that "corporate" news lies all the time about everything? who told you that? why do you trust them? why should I trust them?

if you characterize something with such incredible bias, and do so knowing that the resulting impression and information someone will leave with does not match objective facts in reality, then that is dishonest and to me, equivalent to outright lying. this mischaracterization is in basically every single political article, including literally the top story on cnn dot com right now
