Probably not much. As OP points out, this is not even the first time OA accounts have been hacked. It mentions the CTO and chief scientist and a top researcher already got hacked - and in fact, omits that the same researcher got hacked yesterday for a second time. (Yes, really. I have no idea how they all keep getting hacked by bottomfeeder cryptocurrency hackers. It doesn't speak well of OA's security, especially coming right after that congressional testimony...)
