What you're offering here is not an argument but a mental block to actually thinking about the issue described. You don't offer any ideas for 'correcting people's behaviors': how do you propose to address the phenomena of greed, dishonesty and so on, given that people with those qualities are just as well able to make use of technology for their selfish ends?
Our culture informs us of what is socially acceptable (theft, greed, dishonesty etc) and meters out justice through our real social networks of family and friends. For issues that raise to a level of criminality we use the legal system.
I also think it's perfectly fine to make use of technology for selfish ends. That's the real reason competitive market economies function more effectively than command economies. When we all act out of our own self interest we buy the best value good and reward the most efficient producer. (Thiel argues with this and I admit this pattern does not hold in markets with monopolies, cartels, or regulatory capture)
We have a market economy in this space. The platform companies recognize the risk associated with these platforms and try to control it.
People like Thiel are self interested. He welcomes government oversight because he can influence government - but cannot really influence Apple and Google.
