A bit of a dumb title, Nintendo does develop their own emulators to help port content onto newer systems and that's been known for some time.

Virtual Console is an emulator, or rather a series of self-contained emulators that individual games are packaged in. The NES and SNES Mini consoles use emulators to run their games. Hell, even the original Animal Crossing came with its own NES emulator to run playable versions of Nintendo titles you could get as furniture.

It's not "emulators" they have a problem with, it's third-party emulators that supposedly infringe on Nintendo code/IP and the distribution of ROMs, but whether those grievances are legitimate or not is a separate topic entirely.

Nintendo has already sold us Roms it downloaded from the internet before. Or is using open source emulators for commercial purposes while simultaneously suing them off the market.

They're a company - their only purpose is to make money. They don't hate emulation, they hate not making the absolute maximum amount of money they possibly can. Public use of emulation lowers their profits, while their own use of emulation helps increase their profits. It's not some weird enigma or hypocrisy - money is the singular driving factor for every company; every action they take traces back to making more money. This is why we need much tighter regulation instead of trusting companies to "be reasonable" or "do the right thing."

Is this news? Emulation has been supported in official capacities since the virtual NES in game cube Animal Crossing. There's probably even earlier examples. The Wii virtual shop, the Switch has that classic games library and even those mini consoles.

It sued itself in it's confusion!

So what I’m learning here is there is an offical USB SNES controller

If Nintendo was smart, they'd just provide the means to obtain older games somehow, forever, and not the dripfed method of providing games on the Classics Store as part of a subscription where most of the games offered are garbage games most people haven't even heard of before seeing them in there. As well as seriously make an effort to make at least PC ports for their biggest titles. This would be a much more effective method of combating piracy; just provide the service people are actually demanding.

I can understand not providing 3rd party titles that Nintendo themselves don't own the rights to; but they don't even have their own entire catalogue on there.
