[Pure speculation; I don't work in the UI space at all, and at neither of these companies]
I wonder if Adobe is secretly happy about this. They were acquiring Figma at the peak of the market (for growth stock/startup valuations) because of the existential risks that Figma was threatening, due to their collaborative development UX.
But since then:
* Startup valuations have fallen. Ignoring regulatory concerns, a new acquisition deal today would be cheaper.
* Gen AI and Adobe Firefly are the new rage, and Adobe has probably captured back both mental and market share from Figma. And Adobe can now add collaborative features to Firefly, and it doesn't even have to be as good as Figma's to win.
So paying the 1B breakup fee is probably the cheapest and best option for Adobe at this time.
Meanwhile, Figma employees, expecting a big payout, are probably a bit demotivated at this point. And potentially, they might have been working on integrating into Adobe over the past year, so they might have even slowed down in their development pace.
