"people no longer trust the MSM because they're being told not to by politicians, and the fact that they're often caught misreporting stories doesn't help this."

Chronologically implausible. Trust in the MSM has been collapsing for decades; politicians only recently began telling people not to trust them. Politicians telling people not to trust the media is an effect of the fact that trust had already collapsed, not the cause. If people had trust and regard for the media, then politicians, another group that people have little trust and regard for, telling people not to trust them would have had no effect.

Personally, I can't help but notice that almost nobody seems to propose that if the mainstream news organizations want to fight "fake news", maybe they should make the effort to become more trustworthy. Not make an effort to appear more trustworthy, but to become more trustworthy. I think it says something profound about our era that this hardly even comes up.
