@alex Obviously it's only about money.

It's preposterous to use "open source" to refer to publishing hashes, as hashes themselves don't qualify for copyright, as they lack the creative aspect, so any such release of the hashes won't even qualify for the osd: https://opensource.org/osd/

Sure a large enough collection of hashes may be creative enough to qualify for copyright as a whole, but extracting the hashes from such collection won't create a derivative work.

I'm more driven to eliminate "open source" the more I see it being used as such a vacuous buzzword.

It's merely the *right thing to do* to publish hashes of known illegal images, so an appropriation response to such images can be taken without having to look at the images, but of course these proprietary software companies will never do the right thing unless they're forced to.
