But does it SAY that somewhere on the page where one downloads an 
installer, or on a printed piece of paper if one receives physical 
installation media, or in a readme file that accompanies the installer, 
or, ... ?

Does it even say that when you run the installer?  (After I uninstalled 
7.0.0 and ran the installer for 7.0.1, I received no such notice even 
though I still had 5.2 and 6.0.3 installed.)

Why the secrecy?

Is one supposed to intuit the answer?

Hence my complaint -- and it's a complaint, as I said, much more 
generally applicable than about Mathematica.
