Hi Danny, thanks for your insight about this topic. As someone who works with licensing at Google can I get an idea of what would happen in this scenario.
Let's say Facebook has a Patent on something like `Components`, `Unidirectional data flow`, and `virtual DOM` which were core to React (of course, we don't know for sure). Now let's say a framework built at Google using the same ideas as `Components` and `Unidirectional data flow` under MIT. From what I can find about patents is that if you have a Patent on the eraser then that prevents anyone from building the pencil or at least the eraser can sue for patent infringement. Does this mean the framework that was built at Google under MIT can still be affected by Facebook? If that were the case can we assume Facebook wouldn't sue Google for the same reason as start-up wouldn't want to sue Facebook for patent infringement? What if a startup were sued Facebook for patent infringement and Facebook counter-sues for patent infringement because of use of `Components` and `Unidirectional data flow` in the MIT Google framework do you think Google would step in to help since the startup wouldn't have enough money to take on the counter-sue?
The idea here is that no one knows for sure what Facebook has for Patents on React yet the core concepts that were introduced to the community is wide spread.

Angular 2 is great, just look at all the features you get: WebWorker, Server-Side Rendering, mobile, progressive web application, Lazy loading support, Router, Material Components, Precompile your app. Tree-Shaking support, fast rendering, CLI, and TypeScript. The framework is backed by Google and Microsoft
