Seems like a strange decision unless they know more than said in this blog post to end a relationship that could benefit both sides.
That said I'm fiercely opposed to organisation's like the Ada Initiative since they are inherently discriminatory in nature, I'm in favor of Egalitarianism.
If you don't think they are discriminatory imagine -
---- "The Turing Initiative - Supporting men in open technology and culture"
"The Turing Initiative welcomes men of all kinds, and specifically welcomes trans men and genderqueer men. We strive to be an intersectional social justice organization." ---
We shouldn't be demanding equality for one group or another we should be demanding it for everyone.
Ada Initiative - Support all people in open technology, That I would donate to.
