    Windscribe vs Proton VPN opinions
    Most users think Windscribe is a great alternative to Proton VPN.

    proton is big privacy tech and big privacy tech can turn very easily into big tech so i personally do not trust proton for that reason and windscribe has stated in their blog multible times to not start other projects because that someday will go wrong with user data. and they offer a way better free plan.

    I don't like that the Firefox add-on seems to detect uBlock Origin and suggests using its own blocker instead. A trustworthy VPN should keep its nose out of people's stuff. But at least the free tier allows using servers in more countries.
