I entirely disagree. By buying and owning shares of Exxon, you’re contributing and supporting the oil and gas industry. It’s completely a choice, as opposed to driving a car which is a financial necessity to some.
If you want to kill a business, stop buying from them.
I'm not opposed to car ownership, but office workers don't need 450hp, 2.5t street tanks to cruise around in cities.

Finding a business where the fundamentals and the price converge is extremely profitable, it's what all investors, especially hedge funds, do. A large convergence is unlikely to exist in a market system.
the lower the price is, the more buyers there will be. The company does not change as its price moves. Every decrease in price means investors will get more for less.
