How can evil™ people stop us from creating free maps? It seems that /not
helping/ us is the worst they can do. And I don't think we really need
their help, we can create excellent free maps on our own.

... or if you *do* want to publish it under an equally open license, but
unfortunately it's a different, incompatible share-alike license
... or if you want to publish the result under an even *more* open
license (say, CC-by, or CC0)

data with NC restrictions)
SA certainly has benefits, and given the current situation is likely a
sensible choice for OSM, but claiming that there are no drawbacks and
everyone benefits from it is clearly not true.
