I don't know what to think about this acquisition. What I do know is that the FTC should pick their battles in a different way. There are at least a couple of other tech companies (Google, Amazon) that should be broken up because they're monopolies and I don't know why nobody at the FTC seems to be looking at them.
Breaking an existing company up into multiple smaller companies is an order of magnitude more difficult for a US regulator than stopping a company from buying another one. The FTC is running face first into a legal system that has methodically chipped away at anti trust law for generations. That's the obstacle here, not picking the wrong battles.
The big thing was they did great co-authoring. Adobe tried and failed at it multiple times and started losing market share to Figma, so instead of competing they just bought it. Like they did with Macromedia.
