stick to the facts. The pictures show two of the exits with the doors fully open but no slides, just passengers jumping. I could understand where you were coming from if the doors had not opened with the fuselage "twited and broken" as you put it, but they were open and the slides had not deployed.
Facts
What we have to look at and hear is evidence. For the armchair analysts here the facts do require experience and/or analysis and typically follow an investigation looking at all possibilities.
My cursory review of the photos seem to show that chutes are visible under the open doors although by the time the photos were taken the all the chutes appeared deflated.
So as armchair analysts are we to assume that these visible chutes were
not deployed, deployed but unusable, or deployed and usable for a period of time. Thankfully the chute designer and other experts are available to examine this evidence for us and to provide facts via the Safety Board.
