Considering that the Steam Deck is more expensive than the Switch, arguably every SD player using Yuzu is several lost sales for Nintendo.
Nintendo is somewhat bringing this upon itself in my opinion and I don't feel much sympathy for their lost profits, real or imagined.
This is why they are going after Yuzu in the first place...Because Yuzu makes it easy to pirate Switch games and the pirates feel entitled to play those games on a more expensive device than the device they claim is too expensive.
Given this discussion started around whether to boycott Nintendo or not, it seems that you're not a Nintendo customer at all. So I'm not really sure what you would be boycotting?
And Nintendo is okay with that. If you're never going to be a paying customer, they don't care what you think.
Regardless of that particular commenter, many paying customers of Nintendo have the same attitude that they will only emulate switch games.
I think “many” is probably a bit much.
As for releasing games on PC, I don't see any reason why they would? Developing for PC is much more difficult than a single console, when it comes to handling the variety of hardware, anti-cheat, etc. TOTK and their Mario games are system sellers, with the former even releasing alongside a special edition console and pro controller. Delaying the release of these games to add dev time for a PC port is never going to be worth it.
Personally, I paid for a copy of Tears of the Kingdom when it came out, but only because I had a Switch I could borrow from someone to play it on - if I hadn't had that option, I wouldn't have bought a Switch just to play one game, and I just wouldn't have bought the game at all.
Had they released the game on PC as well as Switch, I would have bought it for PC, but that's not an option. As it stands, either you have to own an overpriced and underpowered console, even if you only want to play one Nintendo game, or you can pirate the game and play it on PC, and have a much better experience than on a real Switch.
