Re: Focus on HTTP/Web breaks everything else
There's also the fact that example.com, example.net and example.org are required by the IETF to be unresolved, which is something I've used in tests in OSS projects. Tests that turned out to fail on Verizon fibre connections, because ISPs getting search revenue is more important than working applications.
All three resolve domains and ping from here as 184.108.40.206, which is registered to a resident of Santa Monica, CA so is unlikely to be anything to do with Virgin's munging. If you look at them with a web browser, they all show the text:
This domain is established to be used for illustrative examples in
documents. You may use this domain in examples without prior
coordination or asking for permission.
And, as a link on this page says they are IANA reserved domains and adds that "These domains may be used as illustrative examples in documents without prior coordination with us. They are not available for registration or transfer", I think you're wrong in claiming that they should not resolve. Did you check your assumptions before posting?
