Good, you understand. Now stop claiming that K
must be uniform when C is fixed. It might be, but
it might not be.

but what can you conclude.

That if we do not know whether or not M is uniform,
we do not know if whether or not K is uniform when
C is fixed.

Thus

If we consider only the OTP without considering the
prior probability on M, we do not know whether
of not M is uniform. So if we consider only the OTP
and a fixed C we do not know whether or not
K is uniform.
