I agree. He's not really wrong; the Neo-SSPX does have big problems. But.....his understanding of the situation in the Catholic Church is still young and minimal. He has perhaps been influenced by people who have an agenda. When he is able to stand strong in his own Faith, and understands the situation from a broader POV, he may adjust his views. Time will tell.
Besides the Crisis in the Church, it takes time to understand Roman Catholicism. It doesn't happen overnight. And as others have pointed out, I wonder why he hasn't investigated Eastern Catholicism. Maybe he has, and we aren't aware of it.
I'm actually surprised at how mature his knowledge actually is, where he can distinguish among various nuances of the different positions, SSPX (R&R), Resistance, SV, etc.
So, what often happens is that people become R&R, and then stay there for a while and then after some study conclude that there's a problem with ecclesiology, and then slide over to SV ... but it takes time.
He's moving quickly here ...

At one point he said something about how he's 75 and wants to make sure he gets Last Rites.
