HTTP is fading away, and for good reasons.
But ocassionally a website that runs on HTTP can be useful, such as in captive portals. This site serves as a permanent memorial to HTTP and pledges never to switch to HTTPS.
But be careful, it could have had ads or malware injected and likely was spied on, by ISPs, governments, hotspots, and other malicious actors. And it also suffers a ranking punishment.
