No, Photon is doing "Massively Multiplayer Online As A Service" (did you even read their page?).
And actually they are running game loops, but you can't inject code into them unless you run their software on-premise
So you are seemingly contradicting yourself. 1st you said that "they are doing that." Now you are saying they are also doing "Massively Multiplayer Online As A Service" -- but in a quite different way than what I specified. So yes, I did read what you posted. Apparently you only carelessly read mine.
