"We really need a law like that in the US, as it is morally and ethically wrong to assert an accusation as fact without being willing to back it up with something to substantiate that accusation. I think I will write my congressman and ask him to propose a law to that effect. "

In this case, I hate to disagree, but I must. The reason? If you give the Congress any rights to restrict free speech, you weaken First Amendment protection. That is a very bad thing.

If they got ahold of making a law like that, they could then simply make it illegal for information which damages a company's case(such as we have been providing for FREE) to be against the law to reveal.

That would be foolish, but a likely outcome, given that we have a certain group of people that want to remove our rights in power now. I think we ought ot have rules about ethical business behavior - no doubt. We should not have people restricting free speech or we would only have the trade rags telling people what to believe.

That would be a very BAD thing.

For those reasons, I would argue that writing your Congress person is not a good idea. There are laws on the books which cover libel and slander. I don't think we have done that here. We are providing a service - warning people by informing them of the truth about the so-called presentation of evidence (none).
