Just nationalize the company. Make shareholders fear this so much that they keep executives in check.
Doctors selling you fentanyl so you can be sedated for surgery is a good thing.
Drug Dealers selling you fentanyl so you can get high is a bad thing
Of course they care about you getting high, that's their sales pitch
Even if it is as simple as "do you want to get high?" drug dealers absolutely do care what your intent is before selling to you
And they certainly care if your intent is to get them arrested and put them in jail
