And it's not just Figma's collaborative features. Figma made fundamentally better decisions about design tool feature set. Better vector editor. Better concept of "symbol" as a component. Much better approach to auto-layout. Much better approach to shared colors / text styles.
At every step, Figma is just a better designed design tool. And a large part of why it's taking the design world by storm is exactly that. Most design work is done alone, not collaboratively dragging elements on the screen. Figma is just a great tool. Sketch is trying to catch up, but they would need to modify a LOT of their past decisions to get to the spot Figma is at.
CADD is a 800lb angry gorilla sitting between you and your design.
Yes, it's a poor craftsperson who blames their tools. And, sometimes it's nice when the tool doesn't fight you every step of the journey.
I imagine the same is true for graphic design.
