If they can emulate a PowerPC system then they can run AmigaOS and MacOS/MacOSX for PowerMacs to run some legacy programs on Windows, Linux, Modern MacOSX, iOS, etc.

There were rumors that Microsoft would port Windows 10 to the XBox One and then convert XBox games to Windows 10 via the Windows Store, etc. Then you could buy or rent XBox, XBox 360, and XBox One games.

Apple had a Rosetta software that ran PowerMac stuff on Intel Macs until 10.7 removed it IIRC. So Apple has the patents and IP for that.

There was also an old ARDI Executor program that ran old Mac 68K stuff in Windows, Linux, BeOS, etc.

ardi software (executor and the 68k emulator) are on github:
