If it is a response to that, you would have to assume that Hickson left because he pushed for or against something relating to working on Flutter. If Google wanted to place him elsewhere, for example, and he left Google because he figured he can bankroll his own work on Flutter and look elsewhere, that'd be in line with this line:

> I hope that Google finally realizes what treasured assets they have here before it's too late. The clock is ticking.

Lowering the amount they're investing in Flutter would definitely be something that would disappoint the ones who believe in it strongly in-house and taking away key people would not inspire confidence. Interestingly none of the tweets ever mention Hickson as being important, which doesn't exactly speak to the source of the complaints being Hickson leaving, but rather a much more general lowering of investment in Flutter.
