Why? You don't have to use it. I have never even opened the WYSIWYG editor on my main Joplin instance. (I started it one time in my local dev build for testing purposes.)

It's being worked on. We had a share-to-joplin on Android for text data, but the module we've used is not maintained properly and broke when we upgraded react-native. On iOS it never worked and I'm not sure what the status is.
