Why be so extravagantly supercilious on the internet?
It's ironic because it seems you're not that familiar with general relativity, and confuse the entire region within the event horizon with the singularity.
Black holes have a causally connected region within the event horizon which is distinct from the singularity, so there can in fact be observers within the event horizon that are in communication with each other, and they can have a perspective, i.e. receive information. The simplest black hole model would be the Schwarzschild black hole (a static, spherically symmetric spacetime, which is empty apart from the central mass) with the Kruskal-Szekeres coordinates, which smoothly continue over the event horizon.
Here's a nice discussion by John Baez about what you might see as you cross the event horizon: https://johncarlosbaez.wordpress.com/2024/11/30/black-hole-puzzle/ https://johncarlosbaez.wordpress.com/2024/11/30/black-hole-p...
To some extent though, what really happens within the event horizon remains speculative, because we can't directly verify any of these predictions about what happens there without actually crossing the horizon ("What happens within the event horizon, stays within the event horizon"). We just make inferences based on the structure of our currently most predictive theory for gravitational phenomena outside event horizons (which is general relativity, ofc)

There is no such thing as "point of view of receivers inside that black hole", everything collapses into a single point or some dimensionless thing or whatever. That's why it is called a singularity. I'd say you're missing out by not reading Baez. He's an extremely gifted thinker and communicator. He knows his stuff
