Although the article doesn't mention the rationale, I imagine the "Rock Lobster" moniker was chosen to follow Lorraine because "Quiche Lorraine" was another (albeit later) B-52's song.
Here's more on the naming [1] of subsequent boards. Nothing to indicate whether or not George Robbins made the connection with "Lorraine", though. Worth noting that the initial codename for the A500 was B52, though. Apparently Rock Lobster came later.
Plenty of us saw Irving Gould as pretty much satan back then, though at the same time it's clear he was essential in funding Commodore in the early years.
You could probably still get a lot of people to pay for an opportunity to egg Gould (if he'd still been alive) and Mehdi Ali (Goulds last executive hire, who conveniently leave out what happened to Commodore under his tenure on his website these days) to this day.
If you haven't seen it yet, Deathbed Vigil is a documentary of the last days of Commodore based on contemporary video footage. It is pretty harrowing, and plenty of the people onscreen seem quite bitter with the management.
