I hope someone has archived the repository so it can be hosted somewhere where those ridiculous Western copyright and patent laws don't apply.

This is an utterly confusing and self sabotaging system. I had lots of issues with displaylink on a Mac. (Daily crash on the first video call of the day for some reason) Does the support care? No. Can I debug using the logs? No - THEY'RE ENCRYPTED! And now they're fighting for customers to not be able to use the hardware.

Save yourself time and money - avoid DisplayLink.

At least part of the effort was posted in mailing list though https://lwn.net/Articles/1078474/ - I hope the recent repository has been mirrored too.

There's also https://github.com/durhamaustin9/DisplayLink-Drivers-Reconst... you may want to preserve locally.
