People generally always want the artist to have control.

What people don't want, as in this case, is for a corporation to have control of the artist's work, and exercise that control mercilessly, thus actually reducing the reach and impact of the artist's work.

(Often, unknowingly to the corporation's own detriment. Having your cars appear in a game is literally free marketing, why refuse that?)

Probably copyright needs to be amended to belong to an individual or a team that comprises not more of 5 people. No corpos can hold copyright or if they do, they must upfront declare the individual/team that holds it.

The engineers at the car company that designed the body in the first place are also artists.
