I don't know if it holds for every scenario, but when it comes to microtransactions or DLC, I judge from the rule: Is this just bitflipping? If they want me to pay for simply giving me a higher value of X resources, it's bad. If they want me to pay for adding new content to the game, that's fine. There is a grey area when it becomes apparent that they removed key content from the "full game" in order to charge extra for it. The new Battlefront 2 debacle shows that. This should also cover the cases of user added mods since making your own content or hacking your copy of the game would be fine.
