Who wouldn't want to be free? Isn't this a bit like asking a slave whether or not they'd like to be emancipated?
Well, there are actual slaves in the lore who express confusion at the idea of freedom.
And there are plenty of Mages who say that freedom is wholly unattractive without Templar protection, from demons or from frightened mobs.
I personally think this question is almost impossible to answer. There are people whose nature tends towards a prioritization of personal freedom, but even their opinions are going to be affected by their experiences. To Wynne, the Templars were rescuers and guardians, and the Circle was the first place she felt understood. She built a relatively positive relationship with Templars. To Anders, the Templars were the kidnappers who took him away from a loving home. He treated them to animosity, and they responded in kind. His entire perception of the circle was colored by that animosity.
Knowing my own nature, I'm pretty confident that I would try to make the most of the situation, but it would also depend on the specifics of that situation. If I was in a circle like the one we saw in Kirkwall, where Templars could get away with the kind of games Alrik played, I would definitely dream of freedom.
