Germany fires cybersecurity chief over Russia ties

This was a political move. A setup.
However, it is probably not a setup, but the minister just took the opportunity of some drama created by the show. The facts all were known when he we was brought into office. There were previous reports.The "news", him attending the birthday party of his former lobbying outfit with permission of the ministry, could be counted as a setup, but it rather makes the ministry look bad as well.
The late night show mentioned in the article. From a quick glance the auto translated subtitles are somewhat ok, the German ones are auto generated already and contain some errors, and I guess some of the humor gets lost in translation.
That all would be ok, if not a couple of huge companies are member of this society. So, if you are in cyber security, this is a little bit too fishy.
This would make sense as an answer, if Schönbohm had a connection with Protelion (other than indirectly through CSRD e.V.). Are you asserting that that is the case?
Otherwise, the links in my mind at the moment are:
KGB — Infotecs — Protelion ... CSRD e.V. — Schönbohm — BSI
where the link "..." is not obviously suspicious (although I'm not saying evidence couldn't be adduced to make it suspicious).
