I'm on the fence on this idea. I think it depends on how well it's doing financially, basically to what extent has Figma eaten its lunch.

I never boarded the Figma train because I prefer the UI of Sketch, as well as its local-first approach and how its file format is publicly documented so I actually own my data. I do worry about it going under though, and if Apple buying it up is the only way for that to happen so be it.

If nothing else it'd keep it out of Adobe's hands which is worth a lot on its own.
