I know a few people that completely block every IP range owned by Google, Amazon, or Facebook.

Most of that works fine, sometimes some shitty websites are on AWS or GCP or load JS frameworks from their CDNs, but the worst is:

You can't connect from Android to their WiFi anymore.

Android pings a Google server, if it can't open a connection, it immediately disconnects. In Android 8.1, there's no way around that anymore. You can try every setting in the WiFi settings, and it won't change a thing.

Can the response be faked?

Probably, considering that domain is HTTP only, but why is this even necessary?

Sometimes I do want to connect to a local network without internet.

Oh I agree, it is a very one size fits all fallacy kind of mistake.
