Login Switch Git repo contains "proprietary" license

The Drupal.org git repo of Login Switch contains a license that is not GPL2+ compatible.

The problematic files are:
https://git.drupalcode.org/project/login_switch/-/blob/8.x-2.x/composer....
https://git.drupalcode.org/project/login_switch/-/blob/8.x-1.x/composer....

Both files state that the license for the project is "proprietary". This violates our Git Repository Usage policy, which states:

All code that is a derivative work of Drupal (typically PHP code, including but not limited to: core patches, modules, themes, etc) committed to Drupal.org's git repository is licensed as GPLv2 and later (official short identifier: “GPL-2.0-or-later”).

To remedy this, please remove the file composer.json from the repo (it is not needed, as there are no external dependencies declared), or replace the word "proprietary" with "GPL-2.0-or-later" in all effected branches.

Please note:
This policy is in the Drupal Git Repository Usage policy you agreed to when you signed up for Git access, which you may want to re-read, to be sure you're not violating other terms.

If the licensing requirement is not resolved within two weeks, the project will be marked as abandoned due to licensing issues.

The Drupal Association has set a Licensing Working Group with the authority to finally deal with issues like this. #3167094: Login Switch module uses proprietary license is the parent issue in the LWG issue queue.

For more information, please see Contacted by the LWG. Now what?.

This notice is not sent to the project owner (Matthew Sherman) through the Drupal.org contact form, as the contant form is disabled.
