You can’t forward ports on mullvad. You know if that matters to you. Airvpn and proton allow port forwarding.
We are swiftly reaching a time where boycotting companies run by people you disagree with will negatively impact your ability to function. Consider abandoning this type of purchasing in the future.
Boycotts are useful alongside militancy. The Montgomery bus boycott for example, was powerful because it gave an alternate path to resolve disputes that were playing out through marches and demonstrations that faced violent opposition.
Boycotts do not generally succeed at their aims if they are not accompanied by that militant wing.
I don’t know of any actions taken by proton that align with the ceos positions you oppose, for example: selective logging and reporting targeted at people in opposition to the trump government. I don’t know of any militant opposition or public demonstrations against those actions even if they did exist.
So I don’t think a boycott of proton would be effective at its goals even if they were explicit and achievable.
More broadly speaking, political action needs to be weighed against the negative repercussions it can bring; which is why in America, for example, lots of political demonstration tends to be younger people with less to lose.
When weighing that decision against having access to a privacy focused (if you don’t give them any identifying information) service, it may make more sense to abandon the boycott in order to get the service.
You could also just use airvpn, but it’s a little spartan and has a different feature set.
Anyway that was the whole point, that it’s easy to jump into an ineffective type of boycott that really hurts you by exposing you to prosecution and also doesn’t actually accomplish your political goals.
