SpiderOak's Warrant Canary Died
Schneier on Security 2018-08-08
BoingBoing has the story.
I have never quite trusted the idea of a warrant canary. But here it seems to have worked. (Presumably, if SpiderOak wanted to replace the warrant canary with a transparency report, they would have written something explaining their decision. To have it simply disappear is what we would expect if SpiderOak were being forced to comply with a US government request for personal data.)
