I read about aviation. I am not an expert by any stretch. It seems that Airbus’s fly by wire system is an exclusive system and that some boeings have some fly by wire but can revert to a physical link between the controls and the control surfaces.
Im sure there is more to it than that.

You are basically correct. To take over the controls on an Airbus, one must overcome or "fool" the computer in order to get it to respond to inputs outside of the control laws.

Boeing allows for direct input of control movements outside the FC control laws in an emergency. That's a little over-simplified, but it is a major difference between the two company's design philosophies.
