It does not explain why the low-probability event of these constants being what they are occurred. It does not explain anything. All it does is move the goalpost for explaining beyond unreachable and trap the inquisitive mind in a box.
As to the predictive power, the multiverse theory does have it. The fact that we can't experimentally confirm it today doesn't mean that it's not falsifiable. I agree, however, that the anthropic principle does not have a predictive power, just like fine tuning, but at least the anthropic principle doesn't imprison the mind and stunt further research by positing an unexplainable super being.
Again, just like with intelligent design, there is not a single physicist who was an atheist first, and then learned about fine tuning and became a believer. Every single proponent of fine tuning was a person of faith first (predominantly Christian but some other faiths too) before they became a physicist. Can you name a single counter example? (that might make me reconsider)
