No one here has given you a good answer because they simply don't know what day-to-day life in China is actually like. If you're a young and reasonably-educated Chinese person, you probably wouldn't notice that the app was taken off the store. If you did notice, you would probably see a message from the government about the app not complying with its standards. Then, you might grumble about it on the internet forums, poking a few jokes at the government, with the knowledge that this is just how tech in China currently works at the moment. Then you'd just migrate to WeChat to handle your voice calls.
