As much as I hate that google kills stuff often, the above comment is missing the fact that facebook also kills stuff often, they just never had any adoption in the first place so you don't notice
But React is more open source and flexible. Microsoft has embraced React and RN via their react-native-windows project, they are currently rewriting it from C# to C++, so it must be important.
They use it for Skype and other products.
Google isn't built on Flutter, not the important parts. Facebook has been building their stuff w/ React. They have over 10,000 components, I doubt they'll abandon it.
Even if they do, React is much more flexible and open, it doesn't have a compiler or language tied to it either. If Google drops Flutter, you're fucked.
