Exactly. It's not that the producers or distributors (of food, content, etc.) are not malicious/amoral/evil/greedy. It's that the real solution lies in fixing the vulnerabilities in the consumers.

You don't say to a heroin addict that they wouldn't have any problems if those pesky heroin dealers didn't make heroin so damn addictive. You realize that it's gonna take internal change (mental/cultural/social overrides to the biological weaknesses) in that person to reliably fix it (and ensure they don't shift to some other addiction).

I'm not saying "let the producers run free". Intervening there is fine as long as we keep front of mind and mouth that people need to take their responsibility and that we need to do everything to help them to do so.
