From Google's perspective being able to block ads with your hosts file is a bug, not a feature.
For what it’s worth, at least in Chromium’s implementation: - The hosts file should still take effect (Chromium can read the hosts file and parse it already.) - The DoH upgrading should not override your default resolver. It works by having a lookup table of providers that support DoH and using DoH if your provider supports it. The list can be seen here: https://cs.chromium.org/chromium/src/net/dns/dns_util.cc?q=D...…
Google sneezes and this is gone.
We didn't think they'd take away extensions' abilities to block ads, and yet here we are.
We've seriously got to pursue breaking this company up. They're the absolute worst.
