As much as I dislike Adams and disagree with a lot of the attempts to paper over a lot of reprehensible stuff, he gave it a try, abandoned it, and publicly denounced it after it didn't work, and even spoke out against the pressuring campaigns done by ivermectin/etc. quacks to push people to waste time, money, and hope on quack treatments.

There's much better examples of areas where he was off the rails than him spending a month on a relatively safe treatment trying to stay alive before giving up when faced with reality.

The man spend a tremendous amount of time trying to discredit the entire medical industry. In the past he has claimed to avoid cancer through prayer. This is part of a pattern.

I'm not sure why that should be lauded. A sample size of 1 (and a trial length of merely 1 month, according to other posts) does not make a convincing study to warrant any public statements.
