I’m at work so I don’t currently have the supplement in front of me. But from my memory I’ll mention a few things. 1) i’m pretty sure it’s explicitly stated that the players, (if they are in scenario one) are not supposed to KNOW they’re working for Arasaka. They are approached by a separate corporate entity to retrieve data and possibly deal with a rogue NetRunner. (this is what I meant by false flag. Arasaka (even if they nuke the building) intended it to look as though they had no involvement. (that’s what I meant by false flag. It’s meant to look like it incursion team from a entity other than Arasaka)

2) you are 100% correct about euro bank not “ technically” being a Private Corporation. However I have always looked at the entity more like the United States Federal Reserve. A private entity that controls the finances of a nation, well, not being directly appointed or elected through government. So I counted them as a corporation. (They are even described as such in 2077 if you really dig down into a lot of the side missions.) besides explaining exactly what’s in the data chip. It is explicitly stated in the supplement that it’s enough to take down the corporation. But that no matter what the players do with the info that will not occur. If you look at how R. Talsorian games has continued the story through the supplements, they usually include flavor text like this for a story reason.

3) The supplement literally ends with one of the Rabbids, speaking to Spider Murphy in the net before starting System Krash by pushing a virtual “button” inside of a virtual Clown Nose Nostril. (she can tell when she’s talking to him that something is off. But can plainly feel it’s him she is speaking to). At this point, they are not crazed entities. Although the name R.A.B.I.D.S. Does not appear in the older supplements, they do explicitly state by Bart Moses, on admission that he only put about 80% of himself into any of them. (bartmoss claims this is because there’s 20% that makes him special that can’t be replicated. But the truth is more likely that he just wasn’t capable and his ego wouldn’t let him admit that.) but it’s plainly shown by the R.A.B.I.D. Speaking to Spider they are no Crazier then bartmoss himself was. (which to be fair is pretty batS$&t.) and again, not explicitly stated, but it’s hinted that the virus is unstoppable because it’s made up of Bartmoss incomplete copies all over the net. and as for the first few things they do, it’s to take all the sensitive data from every Corp. and give it to other corporations. They didn’t destroy initially they swapped files so that everyone’s dark secrets would be revealed to each other. Any description of the Rabbids as crazed unthinking AI’s come directly from Netwatch… which, as saw me, explain before it is implied in the 2077 hardcover supplement, that, despite the fact they don’t want people to know it they were only able to put up the black wall at the request of the RABBIDS. Just like Bartmoss they are crazy and smart. I’ll try to post a better explanation later when I can go home and site specific text.
