As far as blessing certain licenses, I believe that we currently recognize all the OSI and SPDX licenses and display documentation for code with any license that permits commercial use. The full list is at https://pkg.go.dev/license-policy https://pkg.go.dev/license-policy. Analyzing public data is different from reproducing and distributing significant portions. The problem here is reproduction and distribution. Legally, Google's short search result snippets, which quote just a few fragments of a page, are quite different from reproducing and distributing a package's docs in their entirety. https://opensource.google/docs/using/license/ https://opensource.google/docs/using/license/ is a good overview of what a license needs to do and why. I don't know what to say about the "have some trouble believing" part other than to attest that I have personally spent many hours working with (excellent, wonderful) lawyers on these issues. Google really does care about making sure we are respecting the limitations set out in people's licenses.
