Providing a 'shiny red button' to immediately disable flight envelope protections may very well be the last thing that we should provide, .....
Had the ADRs been switched off, or a 'shiny red button' been used, the aircraft would almost certainly have been lost due to grossly exceeding design speeds.
Suggest you stay well away from B777 & B787 aircraft because they have a "shiny red button" (called PFC disconnect switch on the overhead panel in the flight deck) and the aircraft design utilises envelope protection in all of its functionality rather than envelope limiting.
