That doesn’t provide any guarantees that he’s not evolved into, a crank with money.
Looking at Physics historically there are multiple examples of scientists who did productive and fully credible work in their prime and later ended up stuck on crank theories.
It doesn't prove anything. It does make his Jordan comparison disingenuous at best. It's weird enough to gatekeep posting theories (nobody has to believe or even seriously consider them!), even odder to do so for a PhD holder in the field.
Disagree. It’s not weird at all, and I would say quite productive, being that a billionaire crank is a potentially dangerous, with nearly unlimited ability to attempt to spread his influence countering it requires people to speak up.
By the same token, why should i take anything kromem says with anything but a grain of salt ? What are his credentials ? as far as anyone "being swayed" is concerned, he's a random on the internet. He's not changing minds.
You'll have a much better time telling people how and why those "billionaire crankers" are not making sound arguments than trying to gatekeep what they say. Even then, that's no guarantee.
all in all, the idea that people "speaking up" in this way does anything at all is fairly wishful thinking.
