In terms of trust I do trust Airbnb. They supply a fair number of bookings to us and payments have always been on time.
In terms of what makes me distrust Airbnb it is slightly harder. Basically it is stories on social media (including this community centre) where people have been let down by Airbnb in terms of dispute resolution, payments etc. I try to file these in the 'there are always going to be issues but only the bad news gets heard' bucket.
Where I do not fully trust Airbnb is that it is, understandably, aiming to increase it's profit. I can't prove anything but I suspect it does this by enticing large hosts (or companies that manage many properties) with special deals or special exposure in the search rankings such that others lose out. But again, I can control this by listing elsewhere if they go too far.
Hope this helps
