Twitter doesn't turn a profit, do they? If they get a couple months of losing users, that could easily pop their inflated stock. I'm not sure this is a good move for them.
IF they don't turn a profit, doesn't that suggest they're doing something wrong and should change, rather than that they should conservatively refuse to change anything and hope that they will suddenly start turning a profit that way?
There are a lot of things businesses can do to increase profits: They can get more users, they can cut employees, they can move their offices to cheaper areas, they can pursue important business deals, and more.
If a plane is off-course, you wouldn't go to the cockpit and start flipping levers and pressing buttons at random. But you could make the same arguments you've made against a person opposing that idea.
