Is the wire protocol copyrightable? If not, then this license only affects the _document_ itself, not downstream implementations that may _use_ the document.
And if there is a differently-licenses _implementation_ of the protocol, one would assume that it is possible to implement (or just use directly) that implementation without any reliance on this specific specification document.
In other words: IANAL but I don't think this will accomplish what they want (which is Amazon re-implementing a wire-compatible-with-MongoDB database)
As an example: I (probably) can't scan and redistribute an entire cookbook, but I can bake cookies from a recipe in the cookbook and sell them.
