Then, Anti is the one, who broke that fairness... This also means that every sketches we see, that involve with The Egos, all happens in Jack's Mental World! Beside, we dont really see Egos see each other that much... They just mention one and another... And if that's the case, then, maybe the reason why Jack is in a Coma... Cause of all the events happening in his head... Ever since Anti entered, The System is completely destroyed, maybe he isnt talking about Computer System... But Mental System.
Edit:
Also... Anti is a seperate Ego from Jack, he lives within Digital and Mental... (Which is why we can see him appear in Jack's videos, without Jack noticing it, and see him and Jack/Schneep in the same room) and Mental (Cause of the short films/sketches Jack made of him ex: Dark Silence and Chase)
Maybe its not a memory at all, maybe its Anti entering in Chase's dream
Theory: Dark Silence -> Stories Untold - Chapter 4
So, anyone else think that what we saw in Dark Silence is what Jack/Chase’s nightmare/memory was about?
