What does "turn off" even mean? Following the links, it looks like the author is opposed specifically to Chrome pushing sites to migrate from HTTP to HTTPS, mainly because he claims "the web is a social agreement not to break things" and "we will lose a lot of sites that were quickly posted on a whim, over the 25 years the web has existed."
This is hard for me to get on board with. Standards evolve and improve because major players push them. We don't use floppy disks anymore either. HTTPS provides desperately needed privacy and integrity guarantees. And archive.org continues to make historical sites available -- over HTTPS even if the original wasn't.
