Until we find out otherwise. There have been multiple organ harvesting scandals lately. Informed consent has become a marketing concept, no longer a reality.
Organ harvesting of living patients hasn't fully scaled up as a practice yet, but it's definitely a major source of income for some rural hospitals.
I would say accidentally mistaking the patient is dead in any case is hardly the same as purposefully harvesting the organs from people they know are alive to get paid. The article does not state any evidence to suggest they are doing this.
There is obviously going to be some pressure to make a decision to retrieve the organs in the interest of not wasting something that could save another's life as there is a limited time frame where these organs can be viable. There is a huge distinction between that and going to patients that have no doubt they are alive and harvesting their organs.
