Bourdon made a more technical argument: when new console hardware arrives, emulation is not the initial tool that enables piracy. It always follows piracy.
Had we as an industry embraced emulation instead of fighting it, we could have sold it to consumers as the wonderful tool that it is.

"Having open access to a console is pretty much a requirement to make good progress on emulating the system. Without it, you can't do any advanced reverse engineering and figure out how the intricacies of the system behave. And, as it turns out, having open access to a console tends to lead to piracy extremely quickly (and it becomes easier and easier over time, with e.g. custom firmwares replacing modchips).
"Piracy on the Wii U has been doable for close to 1.5 years already. At that time Cemu was just getting started and hadn't released their 1.0.0 version yet. If you own the hardware, it's so much easier to pirate a game than to play it on an emulator. Less technical fiddling, more stability, etc. That's doubly true on extremely new emulator projects. Nobody serious would recommend doing your first playthrough of BotW through Cemu at this time, you'd be spoiling your experience."
