How is this different than http://www.dbad-license.org/
That "is not limited too" sounds scary. I would hesitate to use software under that license. So I guess that is the big difference between the licenses: One allows you to do pretty much whatever you want. The other allows you to be sued for pretty much whatever the author wants.
A few things point to this interpretation.
* All other clauses clauses start with >
* It is followed by "enjoy your free software", which is clearly not intended to be mandatory
* Your interpretation is contradicted by the two instances of "You don't have to, but not doing so would make you a jerk." Those instances are examples of thing that do make you a jerk but are nevertheless allowed.
