Do people intentionally disconnect mid battle?

I've seen a ton of DCs, both early in the game and late.

It really hurts my enjoyment of the game. Like, even if we're getting smoked, I'd rather stick around and work as a team to the end. I mean, it's only a couple minutes. And a DC counts as a loss anyway.

It's really frustrating to see all of these DCs. Are people really rage quitting, or is it just bad networking?

Edit: I just got Splatoon 3 for Christmas, but I'm a veteran of the series. Rage quitting did not seem to be as big of a problem in the previous two games.
