I have mixed feeling about this. Guess they can need the money ... but still. Data goes to Anthropic here. It also will buy influence in some ways, I am sure about that. We could see this with rubygems.org - when shopify threatened to cut funding some months ago, suddenly chaos erupted. Money buys influence, this is easy to see how.
Nowhere is that mentioned - perhaps Dario loves making 3D doodles on his days off :).
No data goes to Anthropic from Blender. At all. See also: https://fund.blender.org/funding-policy/
And Blender tries to get funding from many different donors so that no single one can have any sway over them. Anthropic, as disgusting as they are, are just one more donor. Epic, Nvidia, Google, CoreWeave are also patrons. I don't worry about that donation.
