GPL doesn’t, but as others have already said, this discussion is not about that. If they want to keep using someone else’s free server capacity, maybe they should be giving something in return.
If you're providing your servers for free and include them as the primary update mechanism to an open source project for millions of websites, maybe you shouldn't use that as an extortion mechanism holding millions of websites hostage.
Taking away access to those servers is one thing, doing it without warning putting millions of sites at risk is another.
