SFConservancy misleads in "update" explaining GPLv2.

[freedomfromruin]

Section 4 is not operative against the grantor of the license, and makes 
no claim to be so.

It is speaking only of licensees and what might be described as 
sub-licensees.

Section 0 confirms that "You" refers to licensees.

Section 4 simply states that if a licensee loses his license, that does 
not cause the sub-licensee to lose his license in-turn.
