Last time, I have no problem honoring a license on code written by others EXCEPT when the license presumes to tell other developers that they must do something with code they wrote in separate and not patches made to the original code. This is not irrational or bull. This presumption that the GPL code should impose itself on other code to force it all to be GPL is impolite at best.

I have no hate for the GPL. It is a license for a community that loves it, but saying GPL code can be freely included in other works is a very strange definition of free. It is also poor for teaching as it brings a burden on the future works of students if they directly use the taught code directly. It is a license that should be evaluated like any other, but it imposes burdens on more than the source written under it.
