Which part of "the colonists chose to live under the Cardassian government" wasn't clear to you?
Which part of - watch 'The Maquis' again - is not clear to you?
Among the many revelations you will have is that the colonists chose to live in the DMZ under federation government.
Also, if the Maquis were really under Cardassian government, then the federation had no right to hunt them down as criminals, etc.
As for the rest of your post, your attempts to blame the victims are transparent enough to be clear to everyone who caress to look at the depicted situation even half-way objectively.
