The American historian Timothy Snyder, an author of book about Wilhelm Habsburg "Red Prince", considers him not guilty of that crime. The researcher as some contemporaries of Wilhelm do not exclude that it was a set diversion of some foreign intelligent forces (i.e. Poland, Czechoslovakia, Soviet Union) that supposed to strike the Habsburgs' reputation and prevent their restoration. That theory is supported by the fact that Couyba under a false name and fictitious pretext unsuccessfully tried to go to Austria, possibly publicize the scandal in Austria.
