If it was for an anti-piracy commercial, it's be better than the one here in Australia.
Sure, titles are often hyped, but in this case it's true. They are considered pirates and they probably go around doing bas stuff to people all over the Decolora Islands.
Why do I think that?
1. Why would Totodile need to be mentioned, it's not like the episode focus's on Croconaw and it's not like they'll be befriending it and spending time with it, so that Ash can mention how much he likes Totodile.
2. Totodile and Croconaw are different. Sure, there from the same evolutionary family, but that doesn't mean Totodile should be mentioned.
Seriously, Ash remembers his Pokemon, we don't have to see him remember them every time the same Pokemon shows up in the wild or with another trainer or if it's a different Pokemon from the same evolutionary family that appears. How much notsalgia do people need, this is Best Wishes, not the OS, not Johto, not Hoenn and not DP.
So, stealing food = good? I'm sure there plenty of food growing on lots of islands that they can eat, why do they need to steal Ash and co.'/Team Rocket's food?
The Pirates are the ones in the wrong here, hence why they've been labeled as Pirates and Pirates/Piracy is not really a thing that kids should think is good. The Pirates are the ones making things worse by stealing from people.
And if people resist, they probably attack them, judging from the scene where Octillery inks Oshawott. So it looks like it's more than just stealing.
