Link to Acamedic Free License v. 2.1(https://www.samurajdata.se/opensource/mirror/licenses/afl-2.1.php) at https://www.python.org/psf/contrib/ is not found. Also, Guido mentioned that version 2.1 seems obsolete and we may need to review that with the lawyer (https://bugs.python.org/issue41328#msg374495).

I've sent an email to our lawyer.

A few options present themselves:

- We could switch to AFL 3.0 (https://opensource.org/licenses/AFL-3.0). This will require some review by our lawyer.

- We could link to another copy of AFL 2.1. Honestly the original one seems pretty odd.

- We could link to the archive.org copy of AFL 2.1.

But looking at archive.org I find this copy:

https://web.archive.org/web/20170827133353/https://www.samurajdata.se/opensource/mirror/licenses/afl-2.1.php

which has the following text, in red, at the top:

Larry Rosen has ceased to use or recommend any version of the Academic Free License below version 2.1

(Note that Larry Rosen is the AFL's author.)

So maybe the first option, get a legal opinion on switching to AFL 3.0, is our best recourse.

I also found what looks like a copy of AFL 2.1 on Python's own wiki:

https://wiki.python.org/moin/PythonSoftwareFoundationLicenseFaq/AFL-2.1

(Of course, being a wiki, this has the disadvantage of being publicly editable. :-)

Yet another option presents itself: do away with the AFL 2.1 and just require Apache 2.0. See https://en.wikipedia.org/wiki/License_proliferation for more on this.

Fixed https://www.python.org/psf/contrib/ to point to https://spdx.org/licenses/AFL-2.1.html instead. The contrib-form page (https://www.python.org/psf/contrib/contrib-form/) already had this change, but the PDF you can download from there still lists the old link.

The Adobe form itself also still lists the broken URL. Only Ewa or Betsy can fix this, I suppose. I'll write them an email.
