Not a new question. When I first got into Linux every one was asking “How can we get everyone to dump Windows and use Linux instead?” I long ago got tired of hearing about THIS year being the year of the Linux Desktop.
The answer is the same in both cases. Make it default, because most people don’t really care so long whatever is default does what they need it to do. Add in the network effect GitHub has and things would have to get incredibly bad before everyone would switch.
The reason everyone uses Windows? Because “everyone” uses Windows. Why does everyone use GitHub? Because “everyone” uses GitHub. Both have become the default. That would have to change.
Same for iOS with the added pain that iOS will kill the background process if you don’t open it back up from time to time.
Edit: spelling
