Except they didn't "supercede" any basic physical laws - just added some caveats.Einstein and QM pioneers did just that.
The "over-unity" community is not made up of physicists trying to work on basic science - it's a collection of cranks who believe in massive conspiracies meant to keep them from their dream of free power. You see this with magnet motors, overbalance wheels, the carburetor that runs on water (but that the oil companies have been suppressing) etc.
Today anyone with a Facebook account can create misinformation - and thousands do. Thus a gullible rube can surround himself with misinformation from literally thousands of sources and claim that their woo is well supported. Free energy is just one of the many such conspiracies out there. It's more a symptom of how easy it is to create misinformation (and much some people want to believe it) than anything to do with changing physics.
This is especially sad because there ARE ways to get what is effectively free energy nowadays - but the conspiracy theorists will never see them. Indeed, once a technology is proven (say, solar-PV or betavoltaics) the free-energy community immediately loses interest in them, and returns to insisting that the government is hiding a secret arc reactor in Area 51 that they got from an alien ship (or something similar.)
