Theirs is the big picture. Slave trade merely takes people and gives them to others for money. Don't see much control happening when so many different owners have slaves. If owners have a disagreement, they could simply pit their slaves against each other or something.

What Templars want is to control 'mankind'. This includes those that 'own' the slaves. They want to make sure that order is retained. Just that a lot of the Templar villains went too far and disrupted their own beliefs of order. Take Cesare for example. In the end he couldn't give a damn, he only wanted to be the best.

So if you look at Liberation, the way they used the slaves they relocated retained a degree of order. Other than a select handful that disliked being kept in one place without freedom to go elsewhere, the rest were happy with their lives.

Seems like Sima answered. :P Slave trade primarily enslaves the body, which is why feelings of revolt are born, but that isn't the case if the mind believes it to be just. Even among slaves, not all of them want to escape, some have accepted it and have shunned any thoughts of freedom. That's how humans are.
