We have an indication they aren’t — they make claims that are demonstrably untrue.
[edit] actually, the website is pretty clear about what they do and don’t do. It’s only the poster on here who’s overplaying the availability, OSS and privacy angles.
The only other response of yours in the thread is that it's not available in Canada, which doesn't seem to contradict any of the claims in the thread title?
I didn't say they were OSS (though I agree that it would be much better if it was), and I actually had no idea it wasn't available in the US app store, since I installed it a while back when it still was. Not sure what's going on there.
