The tweet that the submission is quoting seems way more relevant. Specifically:

> Don't call yourself an indie hacker! Don't call yourself anything. You're building a business!!

Exactly. The person in the submitted tweet is just someone who threw different combinations of shit at the wall until someone paid for it, and that was the explicit goal. To the extent that includes any hacking, it’s secondary. “Indie hacking” is filled with people who just use that term to look cool, same way designers a few years back used to insist they were “story tellers”.
