Although I agree with you for the most part, as far as I understand it, there seems to be different layers to this.

Emulators are legal if they’re built from ground up, but if they use any code from the actual system, it’s illegal. For example, I think Dolphin tried to get on Steam, but they were disallowed because they used a “leaked copy of the Wii Common Code”.

Feel free to correct me if I’m wrong. The piracy talk recently have been kind of interesting, because a couple of the emulator communities I’m involved in require proof of dump for any help such as Yuzu’s Discord.

Because the dev now works at Google, he had to remove the root hiding functions called SU Hide. You can bring it back with various modules, but I was lazy and wanted a install one, do all solution.

Magisk Delta is a fork that brings back SU Hide, and I haven’t needed to install an extra app to fix any apps it couldn’t hide root from.

I use Magisk Delta (a fork of Magisk) on an otherwise stock Pixel 7 Pro. Everything works including banking apps and Google Pay.
