Canceling an event like an NBA season or a Big Ten tournament has a billions-of-dollars impact on the bottom lines of 100s of businesses which means none of these organizations would make a decision in a knee-jerk manner thanks to mass hysteria. They probably thought it through.
They probably also considered the impact on their employees too. The “evil businessman” bit really doesn’t work as the NBA, the NCAA, and hundreds of other businesses are walking away from millions in revenue this month out of concern for their employees and the public good.
