Analysis

There are two possible Percy Weasleys, and unfortunately we do not have the data to know which is the real one.

The Collaborator.

The first is the collaborator. This Percy is wilfully ignorant of all that is going wrong in the Ministry until it is nearly too late. He blindly trusts that those in authority will, do, and have use that authority rightly. Because they use their authority correctly for the common good, they are justified in their actions. He has, after all, been raised in the shadow of Dumbledore's utilitarianism, and so this is no surprise.

This Percy honestly believes that those new to the magical world have done something morally reprehensible because he has been told that they have done so by a senior Ministry official. Such a senior person would never lie about such serious official matters, would she? The very idea is unthinkable. Because of this, he continues to work for the Ministry throughout the period of Riddle's control over it, apparently in a position in a position of trust (we do not hear of his demotion).

This Percy is well represented in works such as, but not limited to, sbmcneil's Remember.

The Infiltrator

The second is the infiltrator. This Percy, either of his own initiative, or at the direction of Dumbledore, does know that something is wrong, but believes he can do more good estranged from his family than united with them. He secretly sabotages the work of the so called "muggleborn commission" or in other ways acts as an Order of the Phoenix spy within the Ministry. He is estranged from his family because he does not trust them to be able to pretend to be estranged, and only by being estranged can he manoeuvre himself into the position of trust necessary to be an effective spy/saboteur.

This Percy might not have felt able to explain all of this at their reunion at the room of requirement, and may have settled for appearing less than he is, so as to continue to be as effective as possible. The time for clandestine action was over, and what is important is that he be allowed to continue to act, not that he get the credit. This Percy has been acting all along for the greatest good for society at the cost of his personal reputation, what is one more sacrifice?

Conclusion

Both of these are almost equally possible. The second is far more satisfying, the former unfortunately somewhat more likely, and probably if I analyse deeply enough, more fitting with his character as (minimally) revealed in the books.
