The one thing I know about is Penpot see https://penpot.app/ which is by the team that designed Taiga.io - It's fully open-source and I think tries to solve some of the same problems but it's still in beta. I'm not much of a designer but yesterday started to teach myself Figma only to find this acquisition happening. I've resisted installing creative cloud for years and hearing various people's experiences with Adobe makes me feel like this was a wise decision.
