This is not entirely true.
In Normal Law (pitch), some feedback is artificialy maintained.
In Alternate Law (pitch), same, but there is less gain and feedback.
In Alternate Law (general), Valpha_prot is changed by Vstall_warning (g sensitive) There are still speed limits and speed protections available... but, of course, only if the system still have some valid airspeed sources.
In Direct Law (pitch), feedback is direct as you said (but artificial, as electric).
In Back up Law (no power for computers), pitch is changed using the mechanical THS trim.
