This is not a unitary process in quantum mechanics.
I understand that part, but I don't understand why breaking the entanglement
would make things hot, much less become as hot as its possible for things to
be, the Planck temperature.

The firewall is a conjecture. If you want to avoid this violation of quantum
monogomy (a bad term IMO) you then assume there is no transition across the
horizon once this violation starts to happen at the Page time. Of course this
will not happen all at once and at half the black hole mass, at around 90% the
lifetime which for a solar BH is 10^{67} years, there is a transition where the
passage across the horizon is problematic. This lack of transition means by
some means everything that reaches the horizon is demolished. The horizon in a
sense is converted into a singularity.
-------------------------I guess that puts the kibosh on any hypothetical
black hole adventure tour idea, other than the suicidal kind perhaps...
you know, those spendy affairs arranged for inter-galactic gadzillionaires
fatigued after millions of years of existence, dreaming of sweet oblivion, to
balance the white-out overload of endless being. Or something like that. :)
