That’s not correct:
The Catholic Church has always held to the primacy of conscience and taught that individuals must follow their consciences even when they are wrong. (Vatican II, On Religious Liberty (1965), §2)

Did you actually read the rest of the article you linked to?
Here is the paragraph that follows your quote:
None the less it is important to understand the difference between conscience and personal preference or arbitrary private intuition (cf. Vatican II, The Church in the Modern World (1965), §30, on “wallowing in the luxury of a merely individualistic morality”).Conscience is the inner core of human beings whereby, compelled to seek the truth, they recognise the objective standards of moral conduct, indeed the dictates of God’s law, and make a practical judgment of what is to be done here and now in applying those standards (Rom 2:15-16; Vatican II, On Religious Liberty (1965), §§2,3; The Church in the Modern World (1965), §16). Thus the moral character of actions is determined by objective criteria, not merely by the sincerity of intentions or the goodness of motives, (Vatican II, The Church in the Modern World (1965), §51) and all people are called to form their
consciences accordingly.
And this:
How then do we form a right conscience? Catholics seek to inform their consciences according to reason and revelation as guided by Church teachings. They believe that by “their faith, aroused and sustained by the Spirit of truth, the People of God, guided by the sacred teaching authority (magisterium), and obeying it, receives not the mere word of human beings, but truly the word of God.” (Vatican II, The Church (1964), §12). It is to the pope and the bishops that this teaching authority is entrusted. As the Second Vatican Council put it: “in matters of faith and morals, the bishops speak in the name of Christ and the faithful, for their part, are obliged to accept their bishops’ teaching with a ready and respectful allegiance of mind” (The Church (1964), §25).
