Fire the management who approved of the new Yahoo email.
Multi-billion dollar corporations need to FIRE management who approve of making applications (used by millions of people) more difficult to use and needlessly wastes the users time.
The manager or managers who approved the new Yahoo email are increasing the user's unpaid labor hours because the new Yahoo email is more difficult to use. The top manager or top managers who approved of the new Yahoo email should all be FIRED.
Multi-billion dollar corporations should only reward management types who make applications (used by millions of people) easier to use and which allow the user to customize the application with many options to the user's liking.
