You are out of your tree. Change every domestic vehicle I have owned including the Raptor to Amsoil -- never had a problem. Stick to what you know about. Making statements out of your rear is funny but some people may believe that crap lol. I drive in some of the worst conditions that exist for vehicles not NYC lol.
The Ford trans fluid is actually pretty good quality. Not going to get in a debate with you on your brand X oil, but you need to take some of your own advice.
And as for their statement about the old Ford fluid, which was Type F, that is also 100% true as many people used that usually in racing applications to firm up the shifts. It had little to no friction modifier package.
