I don't think they can hide behind antiterror investigations. Main allegation here is that foreign espionage has been facilitated (which is illegal) and that knowingly is nothing done against it (that's also illegal under the term "Strafvereitelung"). This is definitely somewhat different from surveillance allegations which indeed are more politically inclined and can be argued under antiterror investigations. If state authorities would knowingly support industrial espionage they can get a hard time if it is possible to collect hard evidence for it (I doubt that).
