Who runs the keyboards?

Sung to the tune of a song whose name I cannot recall offhand. Anyone want to help with that? :-)

The customer picked the keyboard,
Picked the keyboard,
The whole computer I daresay,
But the customer doesn't pick it today....

Cuz the OEM picks the keyboard,
For the distro,
So there are those who say
That the OEM picks the keyboard today....

But the MS Hardware builds the keyboards,
Build the keyboards,
Their manufacturing too,
So MS Hardware picks the keyboard, they do....

But the Text Services Framework runs the language bar,
Runs the language bar,
And the selection dialog too,
So the Text Services Framework picks the keyboard, it's true....

But the Shell folks expose the default picking API,
The default picking API
That helps the Language Bar work
So the Shell folks pick the keyboard, no quirk!

But the USER subsystem controls the input,
Controls the input,
And the switching too
So the USER subsystem picks the keyboard, what's new?

But the GIFT team designs the layouts
Designs the layouts,
That all of those folks use
So the GIFT team, picks the keyboard they all choose.

Wait! The customer gives feedback to GIFT
Gives feedback to GIFT,
So then in a way
The customer picks the keyboard today!
