I addressed my concerns about the CERN license already. In particular the definition of "Convey" doesn't seem to apply unless you provide a product of some sort to a customer of some sort or release your source code as open-source. Hosted products and commercial use for internal purposes are arguably not covered under the copyleft parts of the license.

It does seem to be the least bad option, though, for most things.
