Since we know that AK and Philip have been working together, perhaps AK hired Oliver to record the K5 to keep them in check. In other words, maybe AK, Oliver and Philip, are all working together.
Oliver seems like the type to not just up and quit his job, unless he already had another job.
I think Oliver may already be on AK's payroll. I'm guessing that, because why would AK allow Oliver to be at her house and potentially learn of all their dirty deeds?
I can see him working for AK in some capacity, but the filming, especially the night she was shot, I can't see her letting him be a part of those dirty deeds. I lean more towards Philip with that because of the missing time he had with Oliver.
