... there came one question up in my mind?

Can ActiveState forbid me to use python versions downloaded from this page https://www.python.org/downloads/?

Especially for Windows and Linux?

I ask, because they are listed as authors in the license.txt.

    Hey Nikolai, Zak from ActiveState here. Even if we could, we wouldn't want to forbid you (or anyone) from downloading community releases of Python.

  • Hey Nikolai – I don't think I understand. What do you mean?

  • Why are you asking this? Specifically: where has AS made the statement, "You are not allowed to use Python!"

Not by virtue of exercising the copyright on their contributions, no. They could if you were an employee of theirs, or if they had some other valid grounds for being able to forbid you, but not simply by virtue of their copyright.

ActiveState have already unilaterally granted you the right to use that code through the above licensing declaration. Like all free licences, that licence is irrevocable once you've relied on it, which you have done by availing yourself of a copy. The PSF could suddenly decide to cease distribution of Python altogether, but that wouldn't affect the licence status of copies already distributed.
