Through indirect action.
People keep suggesting, like this post, that to impact something like merchandise on the shelves, the new board would have to take action against that merchandise on the shelves. That's such a sweet summer child point of view.
Think more mob boss. That's a nice store you got there, shame if there was a fire.
In this case, not an actual fire. But, any of a million things that mess up operations at WDW.
Don't like merchandise on the shelves, oops surprise inspection close the store while we check the fire codes.
Don't like the theming of a new attraction, oops that building permit is going to take a little longer, you'll get on the second Tuesday next week.
Don't like an episode of a Disney+ show, oops we're doing power maintenance they will be some rolling black outs next week.
Don't like an entire feature movie being released, oops we just cancelled the entire World Drive project, half way through construction. Just live with the temporary roads for a few years, it'll be fine, no operations or quality impact at all.
I'm sure none of those would impact revenue at all.....
