TBH until yesterday when I saw the article I did not even notice the lightning bolt, my brain was automatically filtering it, and now that I know it similarly to you I probably will start skipping those links (similarly what I do with responses tagged as "Ad"). The reason for it is the same why I use uMatrix, I don't want to provide Google with more information about me.

So unless Google actually adjusts the ranking it is useless to get AMP. I wish though that many web sites would chill down with including so much of JS on their pages.
