"Having lots of profit just means it is a good business."

Are you going to seriously argue that's the case? The companies that created the opioid crisis made a truckload of money off it. Health insurers make tons of money. For that matters, dealing illegal drugs is very very profitable and that's why crime syndicates are involved in it. So is selling weapons to the military, or generally involving yourself in foreign wars.

Thankfully Google, Facebook etc have not had the kind of negative impact the opioid crisis has, but there's a proven record of negative impacts like the whatsapp lynchings.
