Ruth & Rindler: more quantum confusion (General)

DAVID: The following dicussion of Bell's inequality thought experiment, reminicent of Wheeler's delayed choice, claims that reality isn't there until we look for it:
 
http://physicsworld.com/cws/article/news/2007/apr/20/quantum-physics-says-goodbye-to-reality -"Some physicists are uncomfortable with the idea that all individual quantum events are innately random. This is why many have proposed more complete theories, which suggest that events are at least partially governed by extra "hidden variables". Now physicists from Austria claim to have performed an experiment that rules out a broad class of hidden-variables theories that focus on realism -- giving the uneasy consequence that reality does not exist when we are not observing it (Nature 446 871)."
 
It appears to me that Ruth's proposed solution fits. Offer waves and conformation waves pull out the underlying reality from 'the other side' so to speak.-The above experiment clearly echoes the Rindler phenomenon "which seems to tell us that not only the properties of quanta but even whether or not there are any quanta is [...] dependent on the observer [...]" Ruth says her theory makes this problem "evaporate", because in Rindler the transaction (between offer waves and confirmation waves) "is simply interpreted differently by the different observers" [one accelerating, one inertial]. I just do not understand how different interpretations by different observers can do away with the problem of subjectivism. I therefore opened this thread in order to get some kind of explanation of what - in my no doubt erroneous interpretation - seems to me a very confusing argument. I suspect from your next post, David, that you are beginning to share my confusion!
