Unfortunately, this is not about fighting mass surveillance, at all. This is just about defending against US spying.
Mass surveillance and spying are NOT the same. Spying is/was a targeted measure and will probably always exist, but mass surveillance targets every single citizen and therefor means "Death to democracy", even if you won't feel it, because it happens gradually and behind-the-scenes ("unfortunate events" will happen more often and we will not know why, how and who).
EDIT: And don't count on ANY government to do anything significant about mass surveillance. Every govt wants it, because it simply means "power over the people". Nothing will happen without an immense pressure from the citizen and consumer. Besides voting, we have a "purchasing power" and we should start using it.
