I have been using VPNs daily for years now. Mostly Proton Paid, at least since I'm on Android. At the moment I use Tailscale with the Mullvad Addon. Best of both worlds. Though in the last couple of weeks I had more and more connection problems. Maybe I'll switch back to Proton, we'll see.
Some people mentioned they don't use their VPN daily or only for specific tasks. In that case, is it correct that your ISP can still see your DNS queries? I know there are encrypted DNS protocols like DoT/DoH, but as far as I know, they don't provide the same level of traffic obfuscation as a full VPN tunnel, right?
Sometimes I just use my Synology as a Tailscale exit node because it's faster, but I feel kind of "naked" since the traffic leaving my server could potentially be visible to my ISP. Is that correct? If it doesn't have a significant impact on privacy, I would actually prefer using my Synology as an exit node. This way, I could save €5 a month and avoid some of the typical VPN-related issues like constant captchas.
