If someone steals my bike, I lose ownership of the bike, that’s theft.
If I pirate a movie, Disney still owns the movie.
If I buy a game, I don’t even own that copy of the game??
In my opinion, theft is a bit more nuanced than that. You pirating the game denies the producers of the game the profit they would have otherwise derived from you purchasing the game
And when you call it piracy, some turbo nerds come out of the woodwork to claim it’s not piracy because piracy implies theft
In the end, anyone who’s not a low tier troll knows exactly the meaning of theft in the context of content creation.
