If nobody joined the safety briefing before and he flew trailing smoke still getting cleared into the box and finally crashed in the public area more is wrong than just a video blogger.
He is right the FAA might have to stop an entire industry if a ton of things don't improve fast.
I have a friend owning a Mustang and I know what it takes to fly it safe and get it insured.

I think that's why Gryder went 'off on one' probably a bit excessively OTT, and has ruffled feathers, because he probably does care about the powers that be putting a stop to everyone's fun, rather than trying to just weed out the cowboys. He clearly hopes the industry will tidy up their own backyard before someone else comes in and does it for them, by removing the backyard entirely.
There clearly are good operations out there, as witness by the EAA immediately grounding their B-17G the other day and cancelling the B-17 tour season this year, after an observant crew members spotted a slight abnormality during a pre-flight, resulting in further inspection which showed fatigue issues in part of the structure.

Utterly appalling.

Yep, unfortunately a lack of professionalism by just a few can quickly ruin things for everyone.
