Chromium is open source and both Google and Microsoft do whatever they want to it as part of developing their browsers. WebKit on iOS is a closed source blob of rendering engine and assorted bits that it is not possible to deeply extend or alter.
WebKit is also open source. https://webkit.org/
Yes, you can use open source WebKit to make a browser for Windows or Mac.
You cannot for iOS. On iOS, you have to use the WebKit framework. Your app will not be compiled with any WebKit open source code.
None of what you said is incorrect.
