Or you already use Proton Mail / Drive etc and want to save a bit of money with Proton Unlimited at 9.99 EUR/USD / mo. That’s why I switched from Mullvad. I do agree that overall though Mullvad is the best in terms of trustworthiness (so far as we know anyway)
As a ‘front page of the internet’ it has been a pretty great replacement for me as it’s where I go each day to just see what’s going on. However, due to the smaller size you do lose a lot of the activity in more niche communities and the sheer volume of posts/comments compared to Reddit. That’s the biggest downside. Still, you also lose the incessant ads/bad UI/UX decisions and ever accelerating late stage capitalism driven enshittification so that’s a big plus.
