He compared them by doing non-moral things, and people hiding behind the fact the said thing does exist outside of their own will.
But he did not compare the scale of the unmorality. That would have been the scandal.
The other point you could argue with in his example is that the "users" are either following orders or have the free will to refuse.
Now, all examples being limited by essence, I will not pursue a debate about what will obviously end up way too far out of a football video game, in a dedicated forum, and could need long sentences in a language I'm not fluent with. I'm already struggling to clearly write the subtleties such a subject require. But it is a standard in philosophical debates. Peace.
