crossed swastika would still be considered distribution of Nazi symbols. there was already a criminal case many years ago where (if I'm remembering it correctly) a student putting "no nazis"-stickers with a crossed swastika had to defend himself at the court. but nevertheless - claiming to be victim of censorship is such a common trope nowadays, so maybe the author even reported himself to get some publicity. he is actually a pretty crappy - or let's say controversial - historian and is not really interesting enough for anyone to purposefully discredit him.
