I‘m sure that Bohemian Coding are _very_ scared of Figma. Just read the comments here - many switch from Sketch to Figma now. Multi-platform is more important than ever, with alienated Mac users switching to Win/Linux, and the iPad Pro becoming a part time computer for many. Having real-time collaboration also doesn’t hurt - Sketch cloud is way behind this.
If they don’t act now, fast, they will soon become irrelevant.
