Thanks for the support, glad you enjoyed the COOL BADGE. Windscribe is full of Easter eggs and quirks, as we don't take ourselves too seriously when it comes to PR and coms (check out our Youtube). Perhaps to our detriment in some cases...
As for Mullvad, I think it's a solid service. If one needs a VPN, and doesn't want to use Windscribe for whatever reason, I always recommend IVPN or Mullvad. Windscribe is spiritually based on IVPN (I used it for many years before WS existed). No advertising, no affiliate program, no BS claims.
At the end of the day, it tunnels your friggen packets to a remote endpoint, nothing more. That alone has virtually zero impact on privacy (safe a few exceptions, like Linux ISO torrenting). The additional/optional bells and whistles we have DO make it more of a privacy suite, but that's only one small part of the big picture.
