You are looking at this backwards. It's all directly because of policy changes, because that's what changed the judicial behavior, which affected upstream police behavior, which affected upstream public's behavior.
Well, since I've known people who worked as loss prevention managers and who did it, and since the news article on the issue posted elsewhere in the thread specifically identified that retailers have changed policies in ways which reduce that, yes, I am reasonably think that they were doing so before and are doing so less now.
> And if crime isn't being prosecuted
To the extent that is a problem in some places (which no source I've seen indicates it is generally, though I've seen some indicating it may be in San Francisco specifically), then that too is not a requirement of the law (misdemeanors are not nonprosecutable) and the same criticism shifts within law enforcement to DAs, it's still not the law’s fault.
Why are you placing blame at everything downstream instead of what actually triggered the changes?
The vast majority of nonviolent crimes here now have no police involvement whatsoever. They just have you file an online report for you to forward to your insurance (if any). This includes catalytic converter thefts that can cost over $2000 alone to resolve, let alone other property loss plus vehicle damage.
Police do choose whether and what resources to devote to investigation after a report. If they never identify an offender because they don't do anything with what they are given by retailers, there are no charges to drop.

Which is a choice by the police.

... and when the DA publishes a policy directive of non-prosecution of property crime, like in SF, police stop spending resources there. It's a catch-22.Under the current "zero bail" guidelines, even felony suspects can be put back on the street the same day. Look up Idris Muhammad, who set three fires while already on probation, was quickly released, then set more fires and busted shop windows.
