Google is delisting websites from DNS and removing entries. It may be more widespread than that. They literally don't have entries anymore. This means it will not resolve an address if you put it in. Even if you have the IP direct, you may not get to it because cloud flare blockss it for ddos protection.
It may be they have been completely removed from the registrar as well
Red 2 may be happening right now
*confirmed that godaddy is axing website registrations
I think most people will be using the default DNS servers provided by their ISP's DHCP server... relatively few would have manually switched to using a different DNS server like Google's, thankfully.
That said, deleting DNS entries to censor sites they don't like might be considered a form of DNS poisoning, if those deletions were allowed to spread throughout the rest of the DNS system.
However, you should be able to get to sites using their IP address instead of their DNS name. Oh well. Looks like the shit is about to get real sometime soon. Finally.
It seems like for now that godaddy is killing off registrations. Dns is the simplest and easiest way for them to get rid of undesirables from the internet even if they are hard to stamp out, like gab currently
