Licensing in this case refers to permission to use a game, such as licensing devans' bustabit code and running your own bustabit. It has nothing to do with any Curaco/random country licenses.
I think not
Unfortunately, government agencies are not interested in whether or not your games are "trustworthy or not", they want to regulate the market which means they want to tell you, what you can or can not do. So if you are found to be offering your games to unlicensed entities, it could be seen as "aiding and abetting".
What I'm concluding here is, the individual game developers need to sell their games only to the licensed parties as the government wants to regulate the market. If the game is sold to an operator that is not licensed by the government, it's risky for the developer long with the client.
