The GPL in most cases only requires that derivative work must also be shipped with the same license. The source code from providers doesn’t have to be distributed by unity, it has to be distributed by the provider.
This is incorrect. The distributor of derivative works in binary form is responsible for providing the source code. They can refer to a server operated by a third party, but if that third party stops providing the source code the distributor remains obligated to ensure that it is still available. The only exception is for binaries which were originally received with a written offer of source code, where the offer can be passed on as-is, but that only applies for “occasional and non-commercial” distribution which wouldn’t work here.

That puts things into perspective, thanks!
