I believe it was their attempt to protect children from unknown people online. I have the app and one of the features is that you can talk to people online in certain games (Animal Crossing, Splatoon, SSB’s, Mario Kart, and I think Mario Party).
Edit: I’d also like to point out that those accessory mics didn’t work with first party games to my knowledge.
There was some public outcry about it specifically from parents who had to download said app and let their kids use it for games. You could later use accessories that would add a mic but it was limited.
