Well if you'd care to look, the claims are backed up by alot of info that Zygon didn't use or didn't have at the time. Dane Spotts made alot of claims which were probably true but he didn't document research like Bill Harris or even Anna Wise has done.
When life is simple you get to practise the art of your choice without all the distractions. If something is successful or has a chance to be then all the Legal and Financial requirments hop on and try to overwhelm it. If it survives that step then it usually is nothing like it was in the beginning.
I doubt you could pass muster if you stepped into the public arena with your program.
