You seem misleaded, and misleading, here, Sir.
If one was to reverse the statement, one could think that non-FBW aircrafts are bug-free. They are not (all).
As you said, IT means bugs occurence, with a greater than 0 probability.
Any modern AP/FMC is an IT system. i.e. prone to bugs. Even if the controls are fully old school (cables) or middle school (hydraulics).
