@Blender blender has been the biggest success story in FOSS since Linux. Why do this? Are there no actual artists or creators involved in these decisions?

Anthropic is also significantly involved with war and violence. Does the project accept those kind of sponsors now?

I feel like accepting this sponsorship is going to have knock on effects for the project that go much further than the size of the cheque you’ll get - you’re damaging trust, not just with the users ( not that the project leadership cares about what users/artists think, clearly ) but with devs and the people who contribute to the project. They’re not dumb, and they don’t have to donate their time if they don’t feel the project deserves it
