So basically what Google is saying is that they control the internet and what people do and if you don't do as they want they ignore you completely.
By not indexing none responsive sites they will not be indexing millions if not billions of sites world wide. Yea Right like their going to let their own stats drop just like that.
Google is nothing more than an advertising agency ( the biggest admittingly) but they don't control the internet, personal I never search using Google or other indexers, I use the Direct internet data base which has everything in it by default.
This problem with Google trying to force you to spend money and be controlled is a very easy fix. DON"T USE GOOGLE
just my 2 cents on this so called major issue your all so worried about.
