I've been concerned for some time that the Internet is becoming differentiated. This appears to be one more sign of it. Let my ISP snoop on and potentially interfere with my connection, or forego doing business. I fear this will only continue to grow worse.
I'm also concerned for Namecheap. Why block this? And the flow was atrocious and uninformative. Also new since December: Once in, www.namecheap.com now redirects to ap.www.namecheap.com that uses a separate certificate from a different root, that uses the obsolete combination of RSA and HMAC-SHA1.
I've liked Namecheap, but I'm not finding this combination of changes acceptable. And I don't like the broader implications, perhaps an encroachment of some form of "true name" prerequisite for TCP/IP level Internet connectivity.
