The main thing that was stopping them from improving in the collaboration / usability department was the fact that Adobe's products are extremely comprehensive – that's how they differentiate. But that comprehensiveness comes at the expense of complexity, makes it harder to have a really tight interface and add things like collaboration features.

The comprehensiveness is what allowed them to win in the enterprise, but it came at a high price. If Figma wants to become an enterprise solution they'll probably end up getting really complex too.
