No, I meant what I wrote.(I think you meant too far from God, too close to Portugal)
The attempts at settling Huguenots were plagued not only by their proximity to Catholic powers (Protestant and French settlement in their sphere of influence wasn't going to end well) but as well by religious issues, not only between Protestant, but between guys leading the expeditions that were often moyenneurs (middle way men) : as in not really picking a side, except when it meant looking loyal to the crown.
Netherlands beneficied from official political support, huge financial ressources.Except when it is not (Guyane). Interestingly, the Dutch also grabbed nearby Suriname.
Huguenots had wishful thinking.
Furthermore, as you said, they grabbed it, not founded it, and in a later date (mid-XVIIth) when the Spanish and Portuguese pressure was far less important.
You forget to take in account the nature of Wars of Religion, and the post-war situation.This is why I am suggesting that Dutch, not French, backing is just what is needed to make this colony successful.
They were as well political than religious, with more or less defined political objectives (mostly imposing themselves).
Fleeing would have been rather the result of defeat, and Ligue mindset was clearly more about mass slaughter than allowing that to happen.
Not only that, but the situation was quite different from late XVIIth in the late XVIth : no Protestant power was acknowledged, and Spain turned Netherlands into its battlefield. Emigration trough Netherland was particularly compromised : you don't move for safety into a war zone.
As for the post-war situation, well, as I tried to point out, Protestants were subject to royal arbitrary that was essentially about crushing any attempt at political counter-power, and maintaining the Catholic domination (Edict of Nantes wasn't a tolerance edict as we understand it : rather the acknowledgement of a de-facto situation, and tolerating it, for a time)
