Oh please, Microsoft uses React in production. Skype app is built on React Native. The business value of a startup has little to do with the tech stack, by the way.
no - you didnt understand what I meant. if you are going to get acquired by a company that has a potential patent dispute (of any kind), then this license is dangerous.
Now, people will still use React - because its javascript and at the end of the day, you can rewrite your web stack faster.
Imagine if you have a React Native app already distributed, a Caffe2 ai pipeline in production... or if your logic is in Bucklescript. Much harder to move away if your acquiring company is in a dispute.
> Facebook ... grants to each recipient of the Software ... license under any Necessary Claims, to make, have made, use, sell, offer to sell, import, and otherwise transfer the Software.
This doesn't say that they're granting you a license to their patents, just their software. In fact, about patents they go beyond to say:
> ... no license is granted under Facebook’s rights in any patent claims that are infringed by (i) modifications
to the Software made by you or any third party or (ii) the Software in combination with any software or other technology.
IMO that's pretty clearly saying you don't actually have any license to their patents. Regarding the termination clause:
> The license granted hereunder will terminate....
It seems pretty clear the only license granted hereunder is the one to use the software; in other words if you sue FB for patent infringement you lose the right to use React/Reason.
Literally every lawyer who has looked at that license agrees that your interpretation is wrong.
Also, licenses like this have standard language; if you're even slightly familiar with how such language is interpreted, you'd realise that this represents two independent licenses to two different things, which terminate in different cases.
Also, Facebook has publically explained what the language means to them, and yes, that would be legally binding on them.
Plus:
> IMO that's pretty clearly saying you don't actually have any license to their patents.
Right, a document titled "additional grant of patent rights" that "grants to each recipient of the Software [...] a perpetual, worldwide, royalty-free, non-exclusive, irrevocable (subject to the termination provision below) license under any [claim of a patent owned by Facebook that is
necessarily infringed by the Software standing alone], isn't a grant of patent rights?
I'm sorry, but literally everything you've said is wrong. I highly suggest you read the analysis of an actual lawyer, such as the one I linked in the comment you're replying to, because you appear to have no clue what you're talking about.
The FAQ is not a binding contract. There is no reason to believe anything outside of the license itself, and the license sais you'll lose it if you file a patent infringement claim.
People lie. It happens. Facebook is not exactly the most noble company in the world.
I think they dropped the ball on it, quality-wise. But that's not a RN thing, that's a Skype team thing. Instagram works just fine and it runs a significant chunk of its code on RN. For that matter, so does Discord, which also runs great.
IMHO, Typescript exists and is of similar quality, far higher community mindshare, and moving from TS ->ES6 is much more easier (in an emergency).
If you write in Reason, the ultimate risk is if you think you will ever be acquired by Google, Microsoft, etc
