Yes, there is no switching of the input power to the USB circuit - the
circuit is being powered 24/365.

Consuming power, admitedly not much per socket but a lot of tiny
amounts soon add up to a big amount. 25 million households, average
of one of these sockets per house hold (some may have none some
several...) 0.25 W each = 6.25 MW,

In the case of Brian's request, if the usb circuit in these wall plates
does produce RF interference then it cannot just be easily unplugged.

Most of them do to a greater or lessor extent, in my experience a
moderately RF quiet one is rare.

Not to mention the fire risk from some elctronics permenantly connect
to the mains and subject to all the spikes and crap on that. And if
it does catch fire no easy way of removing the power.
