Article quotes Thiel out of context, exactly reversing his intended meaning (this is the cost of saying unpopular things, I guess).
“If your product requires advertising or salespeople to sell it, it’s not good enough” and “Technology is primarily about product development, not distribution" appear in Zero to One as the wrong lessons from the dotcom crash. Thiel is saying this to establish what he doesn't believe.
In fact, that entire chapter is dedicated to convincing techies that sales and advertising do matter.
