The repo should have all the history, going back to the last public derosuite commit; it would be highly suspicious for that not to be the case. But if it does not, then expect the questions and demands for sources to persist. And, skepticism may well persist regardless, and justifiably so, since unlike in blockchain, it is possible to rewrite history in git.

Let this serve as a lesson for other devs, about closing sources, even for awhile; open source in the crypto space is not about free software, it is about trust; you can trust the code, and/or you can trust the dev, but without fully open code, you are reduced to the latter. That is to say, the question is not about open source, but about open development.
