I’m sorry dang but no, this is not hostility. Again a startup has a monumental mountain to climb, critical and authentic feedback is absolutely not hostile. It’s valuable food for thought.
The link you referenced is looking for “objects in the mirror” I’m not sure how that’s related here.
Frankly HN has become an Orwellian environment, perhaps after 14+ years I’m no longer welcome here.
Have you ever been to an investor meeting? That is a true hostile environment. Consider this the dry run.
