I like the way you've emphasised everybody. I take it you know everybody personally then.
If EVERYBODY plays with a pad why are these adapters on sale? Perhaps the manufacturers have a cash surplus and like wasting money?
well if you buy a console it comes with a pad
99% of all owners will play with the supplied hardware as intended
my opinion is that kb/mouse is the best control scheme on the planet
but if you have a console you use a pad
whats the point in using a kb/mouse with an adapter if it only mimics the pads movements
you gain NO advantage
and yes i do know EVERYBODY personally
