Given your assumptions, correct.

Oh, shudder, a less drastic result occurs because of these "conniving"
people.

Of course the same thing might happen if these 40 people "connive"
together to set up an out of the way server to preserve non-free.

Only if "majority" and "supermajority" are equivalent -- which they're
not.

In this case, your starting assumption is that no one really cares which
option is choosen, as long as one is.  It's not "subverting the system"
to get results which correspond with this starting assumption.
