This document is divided into two parts, and only the first one is a license in a traditional sense. The second part contains some information about the author's intent, but it shouldn't be regarded as an obligation or contract or even an offer.
We hereby disclaim all exclusive author's rights that were assigned to us by any copyright laws in any coutry,

With regard to this program, author-friendly things include the following:
The author-unfriendly things include the following:
Why may you want to act author-friendly? Well, as the author, I'm going to discriminate users acting unfriendly. I may blacklist the published serial numbers in any new versions; I may also refuse to provide technical support for such users. And, of course, if you have done something, I have a right and an ability to claim that you've done this thing. The right to tell the truth.
E.g. if you will publicly claim that you wrote this software, I'm going to claim that you have not. Hopefully, the truth will be obvious for any objective third-party.
On the other side, I'm going to respect the author-friendly users and be nice to them. They may even be surprised by our support quality and the speed of adding requested features to the program.
So it may be rational for you to obey the author-friendliness rules. Moral aspect of doing or not doing so are entirely up to you – I don't have any control on the morality of others, and I don't even want to have it. As of the legal aspects, see part 1 and don't worry about it.
On the our side, we could write only the first half of the document in a style of legal statement; the second half is written to be perceived by the rational people, not lawers. It saved much trouble that our mind could suffer in other case.
On the abstract side, this is just the way Shareware really works. It's profitable to be a realist.
