It means a GPLv3 project can use something licensed as CC BY-SA 4.0 by converting it to GPLv3, as is required. E.g using a CC BY-SA photograph as a background or a splash image in a program.
And while you technically can’t take the original, yeah, practically everything except “here is the image file alone in a folder” counts as modifying and a derivative work. Resize it, crop it, change a .png to a .jpg etc - all modify the original work.

CC BY-SA 4.0 is one way compatible with GPLv3.

It does mean that anything released under older CC SA licenses aren’t, so they can’t be used in GPL projects. And MIT isn’t compatible at all.

Emulation and emulators aren’t illegal. Yuzu for example got in trouble for distributing tools for circumventing copy protection and dumping roms, not for the emulator itself.

But it doesn’t really matter as nobody has money to defend themselves against something like Nintendo. Here just even the threat of it was enough to get the Ryujinx devs to fold just in case.

If you set your pages and repositories to be viewed publicly, you grant each User of GitHub a nonexclusive, worldwide license to use, display, and perform Your Content through the GitHub Service and to reproduce Your Content solely on GitHub as permitted through GitHub’s functionality (for example, through forking). You may grant further rights if you adopt a license. If you are uploading Content you did not create or own, you are responsible for ensuring that the Content you upload is licensed under terms that grant these permissions to other GitHub Users. -https://docs.github.com/en/site-policy/github-terms/github-terms-of-service#5-license-grant-to-other-users

License can’t really revoke that.

#11 is also pretty great.

Bigger problem is the No Derivatives clause of the CC licence, as compiling or forking the code creates a derivative, so it’s now a project nobody is allowed to use (or distribute) in any other form than their exact, precompiled releases.

In fact, as the GitHub terms of service specifically require you to allow forking - as recently demonstrated by the WinAmp project - I wonder if CC ND is even possible to be used in GitHub in the first place.

The entire network is nuked in those situations, there are no accessible forks left.

And sometimes actual BT beacons made specifically for that reason. It’s one of the ways shopping centres and their apps keep track what shops people visit.
