What is the reason for your objection to paid content? I don’t see how charging money for content is wrong in any way. Said content could easily be deserving of links from HN, I know of no guideline or informal rule that would discourage such practice.
Nothing wrong with charging money for content.
Just don't expect to get on news aggregators if you do.
Don’t expect to be very popular, that much I can agree with. But I don’t think there should be an outright ban.
