what kind of apps cant be updated through playstore/fdroid?
it's not that they can't be (maybe some apps I use can't) but rather that I don't like some things about F-Droid. One of the big things being unreliable app updates. They are often significantly outdated compared to GitHub releases.

"Due to their process of building apps, apps in the official F-Droid repository often fall behind on updates. F-Droid maintainers also reuse package IDs while signing apps with their own keys, which is not ideal as it gives the F-Droid team ultimate trust."
Nintendo would stop them. If yuzu devs want to go to court, they can continue development.
Yuzu devs could do it anonymously, but that's gl on not doxxing yourself, at risk of lawsuit.
