TeamSpeak can only replace the voice chatting aspect. The vast majority of people use discord for text chat.
It's really such a different beast. You can chat in a discord server while you're on your phone when you're unavailable to chat on voice. I know teamspeak has an app, but it was clunky last time I bothered with it, and it's still not that type of experience. People love discord chat, they love the emotes, they love their profiles. I just can't see a lot of people giving that up.
And like I've said earlier, I'm not even sure if most people are aware of the changes or if they even care. The people from Aus or the UK that I've seen on discord lately seem like they're just dealing with the id requirements.
