Earlier quoted context omitted.
I don't think Figma is going to die. It'll be bundled as part of the Creative Suite. It'll add buttons to quickly export your designs to PhotoShop or Illustrator or whatever. It'll probably get slower and clunkier. Not death, just... Adobe.
So a slow death, then. I'm old enough to remember when Adobe acquired Macromedia. They slapped some new icons on Dreamweaver, Fireworks, Flash etc. then completely neglected them until people abandoned them. I pray Figma fares better.
I'd be surprised if they decided to shutter Figma. Now... ruin it by adding a bunch of crap nobody wants like Adobe does with every other product? Pretty likely. But I don't think they'll do what they did to Macromedia. I could be wrong, though.
