I hate to be the pessimist but I suspect it has never happened and why would it? To allow Figma to bring their culture into Adobe will mean massive changes to a lot of people who have been doing a terrible job for years, it will mean power shifting, it will mean older people accepting that the world has changed and they aren't worth their inflated salaries any more.

Even if they wanted to, I doubt they could change, these things just don't scale. 26K employees, most will just carry on doing what they do.

I think the best way to run any of these things is to keep Figma at arms length. Own it, yes, but let them carry on doing what they are already doing well. Don't force them to make their product more enterprise friendly otherwise they will start doing loads of one-offs, complicating it, basically turning it into Creative Suite.
