The article is much larger than CPU level access and control..It discusses high level issues worth thinking about such as communications and social elements
The article lacks any real actionable advice to date it too much.. when will it be out of vogue to suggest reading 1984 to aide in 'anticipation'?
But the value of the article aside.. your language: dated; made me interested in finding out when ME was first introduced and I was having trouble finding any concrete dates of introduction
A lot of your links and their references date around 2015+, yet the authors of your linked book worked at Intel around 2007 and failed to discuss introduction dates
Then I found this at the libreboot FAQ that states ME was introduced into all Intel chips 2006+(o) with the real issues after implementations dating after ~2009+
Also in my search I found some promising leads on overcoming the ME issue:
