No, it's more like mandating map companies do not even list certain addresses in an effort to thwart freight companies from servicing them. A DNS resolver like Quad9 just provides the addresses. There's no allegation here that any infringing content was served by or delivered through Quad9.
I could definitely imagine Google being ordered to remove listings for illegal brothels.
Meh. Some service or another will pop-up to list the fun stuff governments and their corporate crook masters try to squash.
"Will" ? It's already there. People simply aren't so interested in skirting the bans apparently.
Yep. "Offend our commercial legal monopoly for exploiting creators, and the laws and legal precedents we bought order all cartographers to damnatio memoriae your IP and/or location."
No, that's not what the injunction says. It says we have to pay because we were negligent in failing to inspect every web site on every domain that we answer for. To come to an informed determination about whether the web sites contain infringing content. Tens of millions of times per second.
