I can see how you can get that impression. I hope this will help clarify some of your thoughts.
Jason is on the return from 2.5 years of ill health (1 year bedridden) where he became obese. He even had to walk with a cane for a long time. Video below gives a summary of his story, but good to see a person return to the iron game after ill health. His return is now focused on powerlifting rather than bodybuilding and so that is not the best for aesthetics.
His YouTube channel is actually very good. Giving mostly quality information based on science (he has a PhD in exercise science). This includes discussing supplementation (he is a minimalist) and he offers a novice routine (basically 5x5). He is also a bit too honest for his own good.
He started some videos on realistic expectations and fake naturals. I think it was a brave stance to make, but it has developed to quite a storm.
Overall, I think he is more a positive influence. Everybody has their faults.
Eh - if you start this kind of shit, expect to get it back in spades. Poor health or not, he still comes across like just another shit talking asshole looking to start problems and create negativity.
Which is something that I personally don't find to be an admirable quality....
