Riseup currently has a canary[1], they state that it would not trigger for "gag orders, FISA court orders, National Security Letters" which seems like it makes it pretty useless.
Instead, all I see is some debate about PGP.
I can believe that only one submission ever used it. PGP is not friendly to people who barely undersrand how computers work (99.999% of the population), and some panicking whistleblower isn't interested in taking a layman's course in crypto to send some docs.
So why would wikileaks renew their useless(from their perspective) PGP key?

I'm interested to see if Assange brings it back to life.
