ethical or unethical

can any one shed any lights on my curiosity:

Balaji telefilms when it started was a private  company n then it went

public . so is it not ethical and misleading for them (ekta n shobha kapoor)  to display in each

of its series that   the show is

produced by  

                   ekta kapoor

                   shobha kapoor

they r not the only shareholders whose money is being used . so shouldn't it say  produced by balaji telefilms .
