Arn't those doors build to only open to the inside?
Like the interior side of it being larger than the exterior one.
The higher pressure in the cabin will make them fit even thighter into their fittings making it impossible to open during flight, allowing construction to be lighter as you won't need as strong latches to keep it in position as if it were to open to the outside.

Most of them are built to come inside only, but the question was whether or not it would be a good idea to then turn the door and throw it out.

Interestingly, the 737-800 and larger over wing exits are not 'plug-type' doors. They are on a hinge and open upward rapidly when the handle is pulled. They remain attached to the outside of the airplane in an evacuation.
