This isn't reasonable at all in my opinion. It is not a "small batch of rx's that slipped past quality control" there are hundreds of crash reports, involving hundreds of people, rx's, setups, airplanes, etc.
I think horizon should try to find the source of the problem first. It may be a firmware problem, so under rare circumstances the rx fails, or it could simply be poor QC. However, if these are made in the same factory as the other "reliable rx's" why should there be a difference in QC?
My suggestion would be for people to only use the ar500 in cheap sport models. The problem isn't range- it is unexplained loss of signal. WE should all open up the rx when we buy it, check everything is sound, and also range check, check that the failsafe works, and also check the quick connect.
For now, I think that is all we can do.

It strikes me that this situation is just as bad as Futaba's zero-GUID, in fact a whole lot worse because if people are using these faulty receivers then there is a very, very high chance of losing a model.
What should Horizon be doing to mitigate this situation?
Offering all AR500 users a free replacement (including postage)?
Given how much money they must have made in recent times and the scale of the problem, I personally think that this would be the only sensible way to handle the issue.
