The fires didn't reach the WTC inner cores, btw.

That quote contradicts itself in what it describes is a space that had less combustible materials or fuel for the fires - less walls, closet, storage, shelves, etc...

A floor layout of this sort would make the fire propagate faster, consuming more of the fuel sooner - certainly creating an insane raging fire at first, but expending itself and needing to move on to more fuel, probably through the celings, vents or other communicating spaces between floors.

Much of it would probably die out fast unless they didn't design to prevent this from happening. But it seems like that quote actually backs up evidence the fires were going out when the buildings fell down.

According to video, photo and witness reports from survivors, recordings of victims trapped in the towers, and firemen who both made it out and didn't, the fires appeared to be dying just before collapse.

It seems the fires raged at first, as long as they had something to burn, and then the smouldering started - people were overcome by the thick smoke. Firefighters one or two stories below the collapse initiation point reported "isolated" fires they could easily "knock out". Survivors scrambled down out from above the impact zone and didn't report "raging infernos" but the opposite.

The NIST hypothesis doesn't concord with available evidence; they used only what they needed to establish a sequence of circumstance, and conjectured a series of possible scenarios, that backed up the official story, and discarded evidence that flew in the face of that.

Describing the massive support system and solidity of the buildings, for example, as "hollow" and "light" and "full of air" is so specious. The construction of the WTC was more economic than traditional buildings and actually pretty brilliant, but didn't make the buildings more fallible to fire, and certainly didn't make them prone to collapse.
