Maybe a clarification is in order. BUT, this is YC's attempt to make their advice available to the broader community. If you're interested in YC and listen to their advice, you will likely have heard about Peter Thiel's monopoly (see Sam Altman's "How to Start a Startup" series w/ Peter Thiel otherwise).

I'm just happy they're making this advice available.
