I have to wonder who the sociologists were from the 60's that interviewed teens about how the telephone changed their lives. Or perhaps the 70's sociologist who interviewed kids about how cars changed their lives? Certainly it wasn't George Lucas' American Graffiti that informed everyone of the issues?

Audrey Watters blocked Genius and Hypothesis from her blog on Apr 2017: http://hackeducation.com/2017/04/26/no-annotations-thanks-bye

There were discussions about opt-out mechanisms in the Web Annotation Working group (see here), but in the end it was decided that further work would be deferred to to a future version of the specifications.

It's fun (?) that a few months before Nate Angell published in the Hypothesis' blog that Hypothesis was doing pretty well with the Audrey Watters' Test for Educational Technology.
