This happens all the time in software where a product finds great market fit with a small audience and then *absolutely destroys itself* going after a bigger audience.

Potential addressable market is meaningless. Different segments have different needs, different conversion rates.

this is correct, but some questions that might be asked in response to this state of play: what is the value of "reach"? can something be good and useful if it reaches a smaller audience, or do we believe that scale is always and everywhere the goal? Has scaling to the highest reach served us well?
