Okayfreedom VPN is indeed a very good product. Frequently updated, excellent privacy policy, enough servers for Europe, affordable price, secure protocol (OPENVPN). The only disadvantage is the moderate speed in some servers. Okayfreedom HAS a killswitch feature. Its referred as <> in settings section.
The fee for the service is not $29,95 per month but per year, else they wouldn't be competitive enough to stand in the race for a longer time and they have no "secretly adware", if one can read the tos where it is mentioned, that the free version is sponsored by ads. Otherwise i completely cannot understand, why a longterm security expert firm like steganos cannot write a killswitch for their vpn-app - this is really some kind of disgusting and should be changed in the near future - other competitors like nord vpn and windscribe show how this works and how one can build fantastic linux apps too. Stay safe everybody and have a great time ! Cheers.....
I'm in the process of developing a web application and recently discovered OkayFreedom has been attempting to inject Ads into sites. I noticed when I was trying to debug my app and was getting warnings from 'inject.js'. I read the code a bit and it seems to inject ads into HTML forms. UNINSTALL IMMEDIATELY. Make sure you remove the browser extension and perform a malware scan just to be safe.
