The experiences that people report often indicate systemic issues within the platform/product, especially when they are as pervasive as some on the AirBnB platform are.* I wouldn't be so quick to dismiss them.
* I've had two shit hosts that left me up a creek scrambling to find housing, as has my S/O. As a consumer, I am way less likely to use the platform now because my experience has shown me that AirBnB either doesn't care or doesn't have an effective lever to pull to improve this situation.
You can interpret anecdotal data however you see fit - I'm not going to run a survey to validate the hypothesis either way.
That said, I think you'd be foolish as a potential investor to not consider that AirBnB appears to have some unresolved platform issues that could create opportunity for a competing product to make inroads. And while the voices we hear may well be the loudest ones, they can still be influential in driving change, positive or negative.
If there's one in a million chance for a problem to occur in a particular day with a particular host, given a million of hosts, you should expect the problem to occur approximately every day.
