I tried to go to the FSF directory to compare to isitreallyfoss, and discovered that they have started blocking Tor quite rudely, by just giving an unreasoned 403 forbidden. FSF should be embarassed.

Interesting to note openVPN has some red flags on isitreallyfoss, but no mention of the Android app. The f-droid version has no anti-features, but I wonder if f-droid folks should have a closer look.
