[liberationtech] Many VPNs and Psiphon are currently blocked in Iran right now

Thanks Collin, my only point is that Tor *does work* inside Iran unless you
can dispute those numbers.

The only way we can build solutions is with hard evidence not anecdotes
about things being slow or as others have bandied about users being only
interested in speed or convenience.

Clearly Tor does not have the kind of user adoption that Psiphon has, no
one is disputing that.

Effective and responsible social change takes patience and organizing.
We've already seen the effects of this absence in Egypt. We also saw it 35
years ago in Iran and are still  experiencing it.

Social change takes time and effective organizing. I don't care what the
tools are in simply asking for more collaboration and data.
