Mostly what's already been put online--this has always been Gail's primary goal--doing something bigger than Pen and Paper gaming.
Fig is a Kickstarter alternative that was founded by some of the big successful video game people. The ones that did Pillars of Eternity, Wasteland, Broken Age, etc. It's a highly curated place and people actually invest in the products.
Two things not in the article: Paul Stromberg has discussed the fact that a lot of Gary's notes and stuff have been preserved, and will be part of some future project. And Alex retracted his "paper games are dying", instead he feels they have certain limitations.
As I have predicted, there's some congratulations from the casual folks and the more moderate role-players, while the die-hard "fans" who like to gripe about "Gary's Legacy" (which is code for "they are doing something I don't like, ergo it is disrespectful to him") are throwing tantrums, hoping this fails so they can bask in the schadenfreude. Which to me does nobody any good, and the people attacking Gail and Alex are probably being much more disrespectful to Gary than anything anybody does with his remaining IP.
Hopefully good things will come of it. If not, it's no big deal either, life will go on.
