neverssl seems to be doing some weird thing where it uses Javascript to load a non-https link rather than an actual redirect. I can't for the life of me guess why that would be better than a simple 301 redirect.
The primary goal of NeverSSL is to be useful on networks with captive portals that intercept HTTP and block HTTPS (until you have signed in). The JavaScript redirect is at least browser cacheable, whereas a 301 redirect sent via HTTPS would be useless in that scenario as it would fail to load.
Yes, sorry: the other piece is that NeverSSL wants to redirect to a new domain every time you visit to ensure that the page that you was actually loaded from the network and not from a cache, which a cached 301 to a fixed address wouldn't accomplish.
