Pirates are many things, maybe even criminals under international law, but terrorists they are certainly not.
Piracy has to be the canonical example of criminals under international law...

A decade ago it wasn't terrorist groups funding them.
Not if they seize a cargo ship it isn't. Criminals can afford the tools to commit crimes by using those tools to commit crimes.
"I have no evidence, but I can't think of other scenarios so it must be true!"
But seriously, if they were being funded by other groups, why pirate in the first place?

I think it's much more likely it's just easy money and is relatively cheap to pull off.
From the writings at the time 'Muslim sources, however, sometimes refer to the "Islamic naval jihad"—casting the conflicts as part of a sacred mission of war under Allah'
These Islamic pirate/slavers are the SPECIFIC pirates that "The Barbary threat led directly to the United States founding the United States Navy in March 1794.". These are the specific type of pirates that the US Navy was founded to combat to protect ships being seized and their crews sold into slavery.
