I have a question about this as well. Let's say I release a game for free but I'm using a lot of commercial plugins and a few commercial assets.
Is deployment enough? I don't see an option to encrypt the plugins with that, for MZ.
Just to put it out there, there are kind of bunches of threads about this going back through years if you want to see what's already been said
The basic summary is: there is nothing you can do to stop a determined hacker/thief.
Some people suggest using the Enigma executable wrapper, but that can cause technical issues on MV/MZ games.
The built-in encryption prevents anyone from just copying and using your images and audio.
There's a tool from Poryg that makes the plugin files unusable for people copying them out of the game folder.
Aside from that, it's just you going to increasingly great lengths and effort for little point/return.
