Drop Riseup Red VPN
Riseup Red VPN requires to configure OpenVPN and as, @yegortimoshenko[1] mentioned improperly configured OpenVPN may have IPv6 leaks. It is also more difficult to get working and offers fewer guarantees about potentially leaking traffic. Then, why anyone would preferred it over Bitmask (which is currently maintain by members of Leap EA Project and Riseup lab)? And also on their website[2] mentioned as :
NOTE! Are you using a Mac, Linux, or Android? If so, then please use the Black VPN. VPN Red is not as secure, and we are deprecating it!
May be, we can replace it with RiseupVPN( a minimal rewrite of Bitmask VPN client )
