> move their servers outside USA
This is a somewhat popular way that people attempt to protect themselves, but
it actually makes it more likely that you're going to be snooped on for the
most part. As weak as they are, the U.S. actually does have some restrictions
on how they can perform surveillance on their own citizens which don't apply
to foreign countries.
Ultimately, the only way you won't be vulnerable to snooping is if no data
about you is being stored. But we can't verify that; even if DDG released
server source code, we could not possibly verify that what was released is
actually the code that runs on their server, or that it still will be
tomorrow.
