Tsai Hui--sheng says that -Matra had already begun to make preparations for their pull-out as long as half a year before formally withdrawing. During that period, whenever printed circuit boards (PCBs) used in the MRT system or the electrical or mechanical equipment became non-functional, Matra invariably directly replaced them with new ones, never assisting in repairing them, so as to keep their knowledge a trade secret.
蔡輝昇以「刻骨銘心，難以忘懷」，形容馬特拉的不負責任。他指出，早在正式撤離前半年，馬特拉已開始佈局，當時捷運系統或機電設備的電路板若有損壞，馬特拉都以直接換新因應，從不協助修復。
