A combination of people upvoting the title without reading the (pretty useless) article and the article's author using "IndieHacker" in the title which is probably trying to game people into thinking it has any relation to IndieHackers.
Careful with that, indie hacker is a term before the website came along. It could also be a misspelling. I'd rather see IndieHacker as a term than IndieHackers as a brand.
