I consider the association with the botnet to be far less eggregious than association with the bytecoin pre-mine, personally. That is the more likely of the two adverse identifications which have been hypothesized.
I agree with you and I would add that the bytecoin scheme is far more than just a premine. There is deception on top of deception with a side helping of deception. If you want to call out something that is absolute poison when it comes to finance and fraud risk you could hardly come up with a better example. I have idea what if anything BBR has to do with the bytecoin scheme.
