Python programmers and companies with python code should the time and effort delivering new features for their customers instead of spending that time and effort forward porting stuff to python 3 because python 3 isn't delivering enough additional value to justify switching. I think people and businesses with python 2 code would be better off continuing to improve their code bases with new features instead of doing things like this.
