It is interesting for many because they use the product and many feel it is great (see others comments). If it is not maintained, its going to affect them. And many of them are using it to support their startup's installations.

And HN is not only about interesting ideas and innovative startups, its about anything interesting for a hacker. And that could include news about another hacker (or human) who has built a great product and is now in distress. And many would love to help him as a human (to reduce the suffering) and as a hacker (to keep the product alive).
