This is just a hypothesis, but I believe that one of the roots of the problem is a lower ability to retrieve information, caused by increased exposure to advertisement.

Regardless of the above, the problem is actually a big deal, once you consider things like meta-information (such as truth value and reliability of a claim) being also information; so if people don’t get info on their own, it’s easy to misinform them. So it isn’t the muppet failing to see “this is a Lebbit story” and screeching at the “actress” of that video, it’s also a similar muppet saying shit like “ivermectin cures covid” or “jet fuel is making the frogs gay”.
