I should make a backup or two.  I get going after emulation for things that are readily available, but not sure how going after citra is beneficial to Nintendo.

I'm speculating here, but I think Citra just got in the crosshairs because it's the same company as Yuzu, not because Citra was targeted specifically.

So they were emulating current Switch games and then charging for access to their emulator.

Aren’t those literally the two things you DO NOT do w/ emulation?

There is a company behind Yuzu, Tropical Haze LLC, not just fans doing home brewing in their spare time.

I don't know how they funded it or what this company does otherwise. But apparently they have enough money to pay Nintendo $2.4 Million.

There was mention of a Patreon account for Yuzu specifically that people donated money to.

Oh forgot Citra (3DS emulator) was worked by these guys too. They locked down their discord and the GitHub page is now down

That was fast; seems they knew their goose was cooked and decided it wasn't worth the fight.
Others should take note and not repeat their mistakes. Emulation is not inherently bad or illegal, but you gotta be damn careful not to step across that blurred line.

Only fear now is that this will embolden efforts to get rid of emulation in general. As far as I can see yuzu didn't do anything different than Bleem which had the legal battle that set the precedent we stand on today.

They violated copyright laws which bleem didn't.

That was to pay the salary of programmers, that work for yuzu.
Which was why yuzu is in a better state, than other switch emulators, and quicker to find solutions to issues with new games ect.
I wouldn't really call that profiting, if most of that is just kept for paychecks.
