Oh, they also don't give a damn whatsoever. But they have to pretend that they do to a lot more than Wall Street does. They still have end-user customers, who have the power to buy goods and services, which in turn does have some pull, albeit not much.
If Apple buys Disney, and a bunch of people leave or join Apple TV+ due to said acquisition, that will affect Apple's stock, and you can be sure Wall Street cares about that.
Dont think Apple or Disney give a flying f*k what the end customer think... they care more about Wall Street and the money in the bank...
