Call it what you want, but the English reembarked and left the Calabrians on their own. And the insurgency was reduced over by 1808-1809 after Murat took over in Naples. Overall, Maida did nothing to reduce the French presence in Italy.

And control of the Mediterranean did little or nothing overall to affect Napoleon's empire, Sicily or no Sicily. France was a land power, and a sea power can do little or nothing against one unless there is a definite presence against that land power on the Continent. That was the reason that Britain financed coalition after coalition against France during the period.
