Earlier quoted context omitted.
Come on, hosting a simple website/forum is really cheap nowadays. Some websites (wikipedia being the main one) simply ask for donations at the end of the year.
Wikipedia is in different position than other sites. Every time someone posts a link to paywall, everyone discusses how to bypass it. And the people reading HN are wealthy Silicon Valley people. Well, not me but you get the idea. Everyone talking about charging people instead ads - have you ever tried it? Tell me your success stories.
If you're trying to pay salaries, good luck, but hosting costs are very low nowadays.
