They claim to fix the criticisms, see the section "The Bayesian arrow of time."

Who knows how well they did though.

As far as I can tell they're still making impossible assumptions, because certain Bayesian problems can't be calculated under a certain amount of energy, and some can't be calculated at all while embedded in spacetime (excepting time travel, and sometimes even then).

I think it's necessary to increase (on expectation) the entropy in a closed system when measuring, unless you take measuring to be magic and not a physical process.

Thanks, I need to look into those whenever I can find the time, however it also sounds like they are trying to fit General Relativity in there ?

I can't say for sure if this is doomed in the first place because GR infamously is not compatible with quantum mechanics (and trying to match them by force is only going to produce confusion and nonsense), or potentially revolutionary in actually managing to reconcile them...
