Wouldn't just having 1000 canaries be a "legal" way to do the alerting?
A government can compel Amazon to avoid notifying a target (Israel in this case) that their information has been subpoenaed, but can't compel Amazon to lie and say it hasn't sent their info.
Or is the concept of a canary pretty much useless now?
I'm personally one of the "activists" who is trying to avoid Amazon and Google to a practical degree, due to project Nimbus, so I'd be more than happy if their data could be accessed, and even happier to see Amazon and Google just cut ties with them altogether.
And I'm personally one of the "activists" who is trying to avoid Amazon and Google to a practical degree, because they might be ordered by a foreign government (or my own government) to turn over my data to that government and be legally forbidden from saying that they have been required to do this. Or because they might succumb to activist pressure to deplatform me.
