I am not turning down "More bandwidth" in of itself. When a single
party controls too much of the network bandwidth they can launch a
sybil attack on the network to effectively deanonymise users. With
several ports such as SMTP still open, it will also be used for spam
and could really damage Tor's reputation.
Along with this, the MyFamily option prevents users from connecting
from a server group which is controlled by the same operator. This is
to prevent scenarios where a user uses a circuit controlled by a
single party (who can therefore deanonymise them by seeing the whole
connection). Without this set and controlling a large % of the
network, it creates a dangerous concoction of elements for users. Only
the relay operator can set the MyFamily option, the DirAuths etc can't
do it for them.
Fortunately their cluster has a very low % of weighting and right now,
I'm not too concern about it until it grows.

Activist, anarchist and a bit of a dreamer.
