While not appreciating the use of encryption to paywall services, ultimately its the responsibility of the content provider. If the author of an article contributes their content to a publisher who uses this method of encryption, thats up to the content creator; and then I would hope sites like this would just stop linking to them.<p>In reality, this is a major paradigm shift, as it provides a way forward for peer 2 peer hosted content. Imagine that instead of sending the key and providing access, rather your access is based on some other out of band validation system, such that another peer controls your access to their content.<p>Very exciting, but of course this particular perversion of google with AMP is more abuse of technology, solving a problem of publishers at the expense of freedom of information.
