Your example would stand if Rome was the #1 economic power, was also the #1 producer of movies in the world, exported it's myths and culture all around the world all year long, forced their neighboring countries into trade partnerships to make sure Rome's products (including their music, movies, beverages etc.) weren't blocked from competing with local products.

Then yes, people could be pissed at Rome companies also producing "Rome croissant" that were to globally compete with French croissants and take their place on other countries' shelves.
