Well said. It's stunning how ignorant Google is about the web. The vast majority of the web is old and poorly maintained or not maintained at all. It relies on things not breaking, web tech being backwards compatible.
This assumption that behind every website is a team of developers maintaining it for its entire lifecycle is a stubborn and elitist Google fantasy.
They're imperious, but never ignorant. A website without a team of maintainers is beneath their concern. What are you going to do, fax them a nastygram about it?
