To allow for a live avatar. For example when playing Mario Kart online you can see the reactions of your friends your playing with. When you hit someone with a red shell and they make a mad face, you get to see it.
Microphones have been in gaming for a while, this is just the next step.

Don't buy that cute Switch 2 Piranha Plant camera - it's rubbish -
Switch 2’s non-Nintendo games are flopping for so many reasonsThat's a fair point. I also have a SteamDeck so indie games I previously bought on the Switch 1, I would now buy on the SteamDeck. If I only had a Switch or Switch 2, there are advantages to buying handheld versus a PC/Xbox/PlayStation. With the new Xbox handheld thing that likely further cuts into the handheld market and unique feature of the Switch. -

Non Nintendo games on Nintendo consoles are a nice bonus, but only when looking at the lifetime of the console and not the launch.
