I used to be a big fan of the professor in question but i do believe he is part of the problem. The amount of propaganda he has given the anti tasawuf would actually make the assertion he's a secret deobndi more realistic. The idea that ppl are jealous of him is just emotional consolation for his staunch backers. There's a few threads that clearly expose his ineptitude when it comes to explaining ahadith. Yes he is a good speaker and thus gets plenty of airtime but that doesnt make it obligatory for every sunni to blindly follow him.
