What does "control over their work" mean if it's not about losing a sale?

Developers exerting control over a copy that's already in someone's hands has never been a good thing. Too many games have had content ripped out years later because the developer had a change of heart, or was contractually obligated to remove it due to some licensing agreement (unbeknownst to their customers, of course). Both of these scenarios are immoral (arguably illegal) and don't deserve support.

For example an artist may create a character and they don't want that character to be used in relation to politics. Such an action may not affect sales but it would be annoying to happen to the artist especially if the politics didn't match their own. Similarly if it was promoting a religion that was not your own that could be uncomfortable.
