What pisses me off is that some legitimate websites like project goutenberg are all blocked by my Internet provider in Italy and I have to go through a VPN to access them. Same for scribd, vdoc, libgen and so on.
Do yourself a favour and install AdGuardHome/PiHole in your LAN so that you don't have to connect to a VPN each time, that way DNS is going to work and return a valid response back to every single device that you own in the network.
I have two Plusnet Hub Ones at home being used as wireless access points. Both are flashed with OpenWrt and one has AdBlock installed; that one is the house's primary DNS server, with OpenDNS upstream.
Coupled with uBlock origin on all laptops and PCs, the online world is very ad-free.
If I bypass the blocking I am dismayed by how much ad crap there is out there.
Not that I don't recommend something like that for other benefits, but GP could probably just switch their router or devices to use some non-ISP DNS - 1.1.1.1, 9.9.9.9, 8.8.8.8, whatever. It's not blocking specific DNS requests that will fix their immediate problem, it's not blocking them (by not using ISP's resolver).
PiHole is local. You can docker it but you have some.. issues depending on configuration. AdGuard is a pihole like SaaS (that seems pretty good, it's the sort of thing I'd get for my mom).
Old comment, it was from when we all expected they would have just blocked it at ISP dns level at some point, since openai itself is blocking access from the country, yes, you need a "vpn" now. You IQ is ok.
