I would say this is a bold choice for a company whose existing restrictions around third party apps and stores and in-app purchases has already been found illegal. While it doesn't look like they're pushing for it right now, forcing Google to sell Android was something the DOJ has considered as a penalty.
I'm not sure Google still has the ecosystem by the balls. It's very possible whatever Googlers who made this decision are the type of folks who don't comprehend they work for a monopoly that like actually can't do things like this anymore.
