The first rule of almost any project at Google is not to talk about it. It the only job I've ever had where I could not tell my wife anything about my work, aside from how lunch was. My wife joked that Google was almost as paranoid as the DoD or NSA, and thought it was very presumptuous of them to force so much secrecy.
There's private, and there's Google.. I work at Netflix now, and we are quite open in my area. Eg, I can tell my wife what I'm working on, ask her to proof-read my presentations, show her the office, etc.
Before Google, I worked for a privately held company, and it was quite a bit more open as well.
Btw: In February I spent some time looking at the then about 100 committers to Fuchsia/Flutter. Some quite impressive names. I think Fuchsia is a really serious effort in the Chrome team.

There's definitely a lot of ex-Chrome people there, but I don't think it follows that it is in any way in the Chrome team. I'm still curious as to why all of them are essentially creating a new OS, though! Quite the departure from what they've worked on before (and many have been working on the web for two decades).
