[gentoo-user] emerge --sync using tor by default?

[Caveman Al Toraboran]

hi - is that true? 
it seems to be using it automatically when tor.service is running.

what's the point?  e.g. is it made to ensure that we reduce the probability of
having a single man in the middle that may consistently fool us?  by replacing
it by varying men in the middle that is harder for them to coordinate a
consistent lie?

and what do you recommend me to do in order look like the cool kids?
