Wrong. There could be tons of different things going on inside, absolutely indistinguishable from outside, which only sees mass, electric charge and angular momentum. There is no causal connection from inside to outside whatsoever, barring FTL communication.
Unless the “inside” was spontaneously materialized into existence while simultaneously a different chunk of the singularity’s mass blinked out of existence in manners which defy nearly all the physics I know, then there still remains a causal connection from the “disappearance” of this stuff that’s “inside” from the world “outside” at some point in outside time frames, AFAICT. This disappearance of specific pieces of matter and energy seems to more than qualify as a causal effect, when compared to counterfactual futures where they do not disappear.
Also, the causal connection [Inside → Mass → Outside] pretty much looks like a causal connection from inside to outside to me. There’s this nasty step in the middle that blurs all the information such that under most conceivable circumstances there’s no way to tell which of all possible insides is the “true” one, but combined with the above about matter disappearance can still let you concentrate your probability mass, compared to meaningless epiphenomena that cover the entire infinite hypothesis space (minus one single-dimensional line representing its interaction with anything that interacts with our reality in any way) with equal probability because there’s no way it could even in principle affect us even in CTCs, FTL, timeless or n-dimensional spaces, etc.
(Note: I’m not an expert on mind-bending hypothetical edge cases of theoretical physics, so I’m partially testing my own understanding of the subject here.)

Most of what you said is either wrong or meaningless, so I don’t know where to begin unraveling it, sorry. Feel free to ask simple questions of limited scope if you want to learn more about black holes, horizons, singularities and related matters. The subject is quite non-trivial and often counter-intuitive.
In more vague, amateur terms, isn’t the whole horizon thing always the same case, i.e. it’s causally linked to the rest of the universe by observations in the past and inferences using presumed laws of physics, even if the actual state of things beyond the horizon (or inside it or whatever) doesn’t change what we can observe?
The event horizon in an asymptotically flat spacetime (which is not quite the universe we live in, but a decent first step) is defined as the causal past of the infinite causal future. This definition guarantees that we see no effects whatsoever from the part of the universe that is behind the event horizon. The problem with this definition is that we have to wait forever to draw the horizon accurately. Thus there are several alternative horizons which are more instrumentally useful for theorem proving and/or numerical simulations, but are not in general identical to the event horizon. The cosmological event horizon is a totally different beast (it is similar to the Rindler horizon, used to derive the Unruh effect), though it does share a number of properties with the black hole event horizon. There are further exciting complications once you get deeper into the subject.

Hmm, alright.
