What I don't get is how these licenses are particularly binding, in that it's only whomever is
installing the software that is actually party to the license. After the software installation has been completed, say by some rando from craigslist, the copy residing on disk is constrained by only copyright.
It seems like their chilling effect is mostly due to people not wanting to be harassed by legal goons, rather than the concern that the backwards company would actually prevail in court.
