Thanks for the references. I'll check them. I'm extremely biased against the business use of passive voice, to the point of getting so worked up when someone does it with me on mail or slack, that I need go to a quite room and relax for 5 minutes.

Your virtual machine has been created.

I see this a lot in corporate environments, and it's by low level managers thinking every bit of information they're trusted with is so delicate and confidential, they must go above and beyond to reveal the least possible amount of it. Note, in the examples above, it was the manager themselves doing the action. What's wrong with "I did this", "I did that"? This is LARPing as CIA agents (or whatever), and they like the sound of it (I want you to know I have information I can't share, you little shit!).

Mind you, 99.999% of the time, the concealment of "who did the thing" is totally unnecessary. It's only there to reinforce status.
