Still not open source many hours later after multiple people said to put a license on it. Calling something open source when its not is really not okay, and it is hurting free and open source software.

He expressed anxiety and unfamiliarity with adding a license he didn't understand. Not to mention multiple users started arguing over the best license, further highlighting why he shouldn't just trust random internet comments and actually look into it. You're going to harass him for it? Do you own his time for the next week because he made a post on HN? Because that attitude is way more harmful to OSS than what you're up in arms about.
Furthermore, this is colloquially open-source to most people, and you're hung up on semantics. Anybody that needs to care about a license can look and see if one is there. If it's so simple to understand a license and add it to your project in such a short span of time, surely it's simple to check for the existence of one in the first place.
