Meta doesn't allow fair use anymore.
Is this fair use, though? Is the right of a recipient to reproduce a letter just a special case of fair use, or is it a separate law?
But we don't need fair use at all in this situation. The copyright holder has explicitly licensed Wikipedia to use this image. It's just the fact that they didn't license anyone else to use it that stops it from being used on Wikipedia. This is because Wikipedia's mandate is to produce an encyclopedia that anyone else can redistribute if they want.
Meta, on the other hand, has no such mandate.
