You do see the universe speed up. You just don't see the whole future of the universe play out before you cross.
If you cross there are some things you never see. You can take the of your crossing and look at it's past light cone and this will include a last moment that you see before you cross. It's actually the view you see in the sky the moment you cross. Anything that didn't reach your eyes by then won't be seen before you cross.
It's not an infinite speed up, but it is a speed up.
The only difference is we can't return the probe just before it hits the horizon, and any message sent out would not only take eons, but would be extremely red shifted.
You can come back any nonzero distance before you cross. The horizon is defined as the point of no return, so by definition you can return if you haven't crossed yet.
To be fair it is possible that we are already inside an event horizon. If a giant shell of matter was contracting around us then we wouldn't notice and if the mass of that shell was M and it contracts to a surface area of $4\pi(2GM)^2$ then we might be inside and just don't realize it. Life doesn't magically act different just because you are inside an event horizon.
What happens is that shell hitting that surface area could be a no return region so for the things inside the no return region forms when you no longer have time to reach that shell before it hits the critical value. So you can imagine some points appear where they are just too far from where the shell is going to form, for instance at the center of the shell and then at the speed of light the event horizon expands from those points until it hits that shell right as they form the critical radius.
The irony is that shell could be configured with rockets that could keep the shell from getting too small and whether or not an event horizon forms Herr now could be related to whether those rockets fire. And that's the point. Before the event horizon forms you could actually send a signal to prevent it from happening but afterwards you can't it it either happens or not but you have no say.
But the point I'm making is that you feel nothing as the event horizon shoots past you at the speed of light and it happens or not n depending on future events that haven't happened or not bit once it crosses you can't control it.
And if that shell is huge you might live and is inside he event horizon and not known since it takes so long for it to contract to where you are.
OK, but you said you you can't return from just before it hits the horizon, but you can. By definition. So let's say you happen to get out of dodge right before the event horizon but just barely.
Then you need to rush away at bear night speed which means you immediately start seeing in that direction go faster after all the light from those things is rushing towards that event horizon at light speed and you are rushing away at near light speed. So it definitely looks like watching a movie on faster forward.
But this is normal for two paths by hat start and stop at the same time and place to have their clocks measure different durations. It is as natural as two paths from the same endpoints having different lengths.
There way to age the most is to move on geodesics. But there can be multiple geodesics between two events that aren't sufficiently close. So you can't know that you aged the most just because you moved on a geodesic.
But if you didn't move on a geodesic then you did not age the most. And so if you fired your rockets then you know you will be younger than you twin that stayed far away if your twin didn't fire any rockets.
So you might see your twin speed up as you rush towards them but that is just you seeing light signals that were already in route. You really did age less than your twin that stayed away from the event horizon as you went in close and came back right before you crossed.
But that is normal, you could do the same in flat spacetime by firing your rockets.
