Actually, there is a cure — lawsuits. It seems every Ammendment can have some restrictiions — that is if the Dems want them. There is no reason that the freedom of the press can’t also have restrictions when it is blatently obvious when the media is intentionally lying. The Supreme’s have said there can be restrictions on the 2nd Ammendment, on Churches etc. So why not on the most powerful and corrupt part of our society — the press. A few huge wins against not only the media outlet but also the individual and I gaurantee they will be a little more honest.
The problem is: what are you going to sue them for? To sue them you need to show some actual harm was done by them to you, and not just some general “they’re hurting society” argument.
Now if they mess up and slander someone who isn’t a public figure, like Nick Sandman, then they are liable and they are going to pay up. But those cases are few and far between and are probably not going to result in any real change in corporate behavior.
