I am not talking about parsing Python files. I am talking about
parsing {{extend 'layout.html'}}{{for i in range(3)}}<h1>{{=i}}</h1>
{{pass}} and turning this into a python file. My benchmarks show a big
difference on complex pages. If you dig on the list they were
published once.

The issue is freer for who. BSD is designed so that a business can
take over a project and close source its derivative work. The "freer"
part of BSD protects these kind of companies, not the actual project
or its original developers.
