What are people using VPNs for mostly, if they're living in a country without internet censorship? It's either your ISP or the VPN provider, which can log the websites you have visited, so there isn't a clear advantage of using a VPN. Sure the VPN provider may claim to log nothing, but that's hard to confirm and not proven to be true in some cases (related thread regarding Protonmail: https://news.ycombinator.com/ite…
On top of that there's also the value of just having privacy even if the ISP can be trusted. E.g. I might not mind being seen naked by a friend, but I would still prefer for that to not happen.
In general I think a lot of the big providers who have gone without incidents (and without major changes) for a long time can be trusted. I feel the incidents with Proton were somewhat overblown, since their page on legal notices received did mention that they could be compelled to log IP addresses (or at least that's how I remembered it). But even without that, I think Mullvad has been pushing for "system transparency" where users can verify all the software that's running on their servers, which is a step in the right direction towards providing confidence that they are indeed not logging anything.
