Not sure if I want to advance brain science, maybe these companies can be legally held accountable... Or maybe gambling companies will get to the research first and manipulate us.
Sometimes legal and heavily regulated activities can still have devastating results.
Legal != moral
Sure, they said “legally held accountable” and you replied that these organizations are already operating legally.
So then the matter is: should these companies be allowed to continue operating as they currently do because it’s legal? Or should we push for laws/regulations to be changed so they stop exploiting people?
This is not a matter of fact issue. It’s a moral, political, and yes subjective, issue.
So your question, even if you didn’t intend it to, very much has to do with morality.
