So I'm confused networking stuff has never been my strong suit, is this saying you can still be fucked on public WiFi even if you connect through a VPN?
There are some attacks you are vulnerable to on public WiFi that a VPN can help with.
More generally, whoever is transporting your data knows who you are talking to. If you don’t use a VPN, your ISP and whoever owns the router know what websites you are visiting (although they don’t know the specific content). If you use a VPN, your ISP and router know you are using that VPN, but not what websites you are visiting. Now your VPN knows what websites you are visiting, but they still don’t know what the content is.
I hope that helps.
What about DoH/DoT which comes enabled by default in some browsers I believe? This should "hide" your activity from isp/router as well, shouldn't it?
DoH & DoT still leak the domain name (and of course IP address) you're connecting to. The domain name leak can be solved by Encrypted Client Hello but that's still a draft and not turned on for many servers.
