This is correct.

This means we implicitly decided it was more important to ask parties
that are unlikely to cooperate to send fake time information to Tails
users, than it would be to entirely avoid asking servers who generally
don't care about privacy. In general, for such matters, I'd rather
rely on diversity, rather than on a set of "trusted" peers.

IIRC: speed, and simplicity ("good enough" is good enough).
If that's not good enough, I'm happy to take a patch :)
... but we need to make up our mind wrt. tlsdate first, I think.
