re: Is Scott Phillips (American Woodworker) preventing new wood workers from learning proper Joinery ?

I think there is a Facebook page called I hate Scott Phillips. So I guess we look at many things when we build something for a client as in , is it cabinetry so pocket screws work great for that and i have been doing it for 20 plus years and never had a face frame fall apart or a box. The next thing is what your market is, will they pay for craftsmanship and joinery. That is a big part of the business and do they care if they have dovetail drawers or m/t door joints? Hate to bust people bubble but there is a small amount of people that really care. Certain joinery should be used no matter such as a m/t apron to a table leg and pinned is a must.
I think the rule of thumb is that if it cabinetry you use more modern joinery like biscuits, pocket screw etc. For furniture you may use some of the older joinery or a mix of new to old depending on what the cost of the piece will be. For scoot I think each show on TV has it different levels of woodworking and most of these guys are running a race with programing and all that crap that goes with TV.
