Bullshit. You can go to the GRC website and forums to see that he has never changed his opinion on the snake oil of Spinrite for modern drives. And the very fact that he continues to sell something with claims that cannot possibly be true for modern (past 30 years) hard drives (not to mention SSDs) is alone enough evidence.

I cannot read his mind. But my guess is that he actually believes a lot of the nonsense he is spouting, it isn’t malice. That doesn’t make him any less of a crackpot though.
