@creamqueen Just because you didn't pay for a "license key" doesn't mean the proprietary license terms aren't valid.

It's only actual free software that grants you the freedom to run the software without agreeing to anything (GPLv3);
9. Acceptance Not Required for Having Copies.
You are not required to accept this License in order to receive or run a copy of the Program. Ancillary propagation of a covered work occurring solely as a consequence of using peer-to-peer transmission to receive a copy likewise does not require acceptance. However, nothing other than this License grants you permission to propagate or modify any covered work. These actions infringe copyright if you do not accept this License. Therefore, by modifying or propagating a covered work, you indicate your acceptance of this License to do so.
