These "library managers" like Ultra Librarian and SnapEDA are a pox upon the ecosystem. The symbols and footprints have non-open source licenses, so you nominally can't share them. They simply want to get in the middle of your design so that they can monetize you.
That part is very important when it comes to CC licenses. Make a mistake in attribution for pre-4.0 CC license and you are open to being sued by the rights holder.
Cory Doctrow has an article about the background and the industry that sprang up to make use of this. https://pluralistic.net/2022/01/24/a-bug-in-early-creative-c...

I think the link to the Design Exception was broken previously. Also in the definition it's called the Design Exclusion, might want to fix that.
It would just be easiest if every page where you download the design has a copyable license with correct attribution, and a LICENSE file in the download bundle, just like a typical open source project. As is, the license information is kind of buried in not one but two different FAQ parts of your website.
How does the licensing issue actually manifest in a practical sense? By what mechanism(s) could this monetization occur? Is this sabre rattling or are small hardware designers actually getting bills for using premade footprints and models?
