is any access to my news feeds and reading activity given out to any other entities?
Besides any law enforcement agency that can serve Newsblur with a subpoena / wiretap order / whatever?
There’s no information either way that I’ve seen on newsblur.com.
You could always create your own Newsblur instance on hardware you control, running a forked edition that’s had the unwanted “features” removed.
Although this only talks about selling data, not court orders etc.
At the very least, I believe Samuel is in the USA, and I believe his servers are in the USA. Therefore, he would have to respond to any US court orders.
