Mullvad is killing it with its features. Four obfuscation options is amazing to have for people not living in the West.
Literally 
I had to reconsider integrating Mullvad’s anti-surveillance & anti-censorship features (hotly requested on our GitHub and over emails) in Rethink because it seems Mullvad has begun adding non-FOSS clauses to its licenses?
Edit: May be I read the license wrong… It seems like a weirdly formatted 3-BSD.
So.. not a good thing for other developers I see. I wonder why they’re doing this.

I was confused but I see your edit now. I’m not developer so I don’t fully always understand the licenses part of software and what’s possible or not with them.

My bad. Usually we use a script to collect the licenses for our dependencies & flag non-OSF approved ones (in our case specifically, flag licenses incompatible with Apache v2, which includes a few OSF-approved copyleft licenses like GPLv3). When I ran the script on the gotatun package, it incorrectly flagged it (false positive). 3-Clause BSD, an popular and OSF-approved license, is totally compatible with Apache v2.
