Here we are back at you denying facts, or maybe just generalizing too
much.  As several others have put it already:

When "browsing" to openpgpkey.sac001.github.io with whatever reasonable
HTTPS client, you are directed to an IP address.  The web server at that
IP address presents a certificate for (among others) *.github.io.  This
certificate is *invalid* for the originally entered domain name.  No
matter how many times you deny it.

For sac001.github.io, the certificate is *valid*.  Nobody ever
questioned that.  But it doesn't mean the above is untrue.

Stay safe.
André
