Then why has the site become more annoying and less usable over time?

This isn't just a personal opinion. I've heard it spontaneously from various friends and acquaintances.

Granted we're mostly a similar demographic in a single market.

But even so.

I can't and won't speak on behalf of AirBnB, but you should keep in mind that in general:

a) all software grows by accretion until a breaking point,

b) paying off technical debt without solving any concrete problem or adding any tangible benefit is not considered a worthwhile investment,

c) a site did not changed for the worse if the data shows its conversion rate increased.

It's a business whose product transcends the site it's presented on, and exists in spite of the quality of its site.
