I think you’re confusing ‘excuse’ for ‘reason’ here. no one is excusing his behavior, just pointing out that the reason he does it is because the system allows for this kind of behavior. we can see through the veil, but others are being hooked by it because it’s designed to keep you hooked.
it’s the same with other charismatic always online personalities. they’re really good at spinning their bs and people keep eating it up because it sounds good.
