What are you referring to? The cult belief that they are ushering in a machine god or that they strictly care about making as much money as humanely possibly while ignoring the absolutely destructive impacts these companies have had on society?
IMO they are using the cult messaging to distract the public so they take out all the oxygen in the room regarding people that care about the immediate impacts (climate exacerbation, ease of scamming, degrading job prospects, increasing income inequality).
Whenever real concerns are brought up against these companies they are always ignored while claiming the real concern is the fantasy of a machine god turning into skynet.

If they believe they're creating "a machine god" and that it's better it's their machine god than someone else's (which, given the other contenders, I tend to agree with), then all the corollaries you mention are mostly irrelevant.
Whether you believe they're creating a machine god is irrelevant. They believe that they are. It would be helpful if you could create an actually good argument for why they cannot or are not creating a machine god, but it turns out there are no good arguments for why it's impossible to do so. And so... they shall try.
Oh okay, they're all just legit crazy and are allowed to poison the environment, murder teenagers, and ruin the material lives of millions for fantasy level delusions.
Good to know.
