So I guess "Whistle-blower" is appropriate here, but marketing a "batch" processing system as "real-time" seems to be a bit of a nothing-burger in my mind. I think the more telling thing is he seems to have raised this multiple times to various superiors and not gotten the hint that they weren't concerned. Someone at a VP level (especially at Salesforce) should have enough corporate etiquette to get the hint. Unless he believed this would literally be hurting/killing people (and I find the hospital/care marketing laughable) it doesn't seem appropriate to not accept "I heard your concerns but we will still be launching on X." He is certainly not financially liable for an overzealous marketing department. I've certainly raised concerns from a technical perspective to be shot down in launch meetings, particularly around marketing claims. However, at a certain point you do your best and start supporting the team effort.
