To be clear, you're saying that most other VPNs are targeting that audience, not mullvad, right?
(That's what I'm reading)
Streaming services take efforts to block VPNs. VPNs targeting users who want to access streaming services need to work to circumvent the efforts of streaming services. Mullvad does not attempt to do this so.
Yup.
They also don't have an affiliate program, so there isn't monetary incentive for websites to promote it.
