They tried to assist and it fed the dishonesty of the truth movement - the crap about Chandler "forced" NIST to "admit" freefall. Still we have had a bit of fun explaining the free body physics and why parts of a falling sub-system can exceed G. And, in doing that, we revealed that quite a few "debunkers" also get a bit lost in the basics so "truthers" aren't the only ones who don't comprehend basic physics.
I agree but I see it as part of a broader situation.
The "truth" movement was desperate to prove CD at WTC for whatever dishonest or deluded reasons. The mechanisms of the collapses of the Twins were very much mostly in view - only two critical stages with three ways of introducing CD. (Pre weakening of the core, initiation stage and/or progression or "global collapse" stage.) All of those pretty much visible so hard to hide CD and easy to show why "natural" collapse occurred and why no CD was needed. Leading through to strong indications that there was no CD - allowing for the logic problem of cannot prove a negative. So claiming CD with the twins was always going to be a losing tactic despite the debate being dragged out for many years.
With CD of the Twins easily rebutted the situation with WTC7 was a boon to the truthers. All the mechanisms were hidden. Remember that the TM has never put forward a pro CD hypothesis worthy of the name "hypothesis" and meeting prima-facie standard of a "case to answer". All their claims AFAIK rely on reversing burden of proof - in the form of "It looked like CD - you debunkers prove it wasn't". OR "there was therm*te in the dust prove it wasn't therm*te before we even get to prove it wasn't CD".
And lots of us gullible debunkers fall for the trap because we like explaining sciency (engineering forensic) things. Reality says that there is no truther claim worthy of response. "Genuine truthers" - those who realy do not understand - are satisfied with reasoned explanations. But we don't see any "genuine truthers" around forums these days. Most are playing the trolling game and pretending to not understand so basically they are dishonest game players.
And the point I try to make here is that WTC7 collapse suited the dishonest game players or deluded truthers because nearly all the details were hidden. They could keep us going round in circles as we accepted "reverse burden of proof" and attempted the logical impossible of proving a (lot of) negative(s).
Not that many truthers are intelligent enough to make that a deliberate strategy. The reason many of them are truthers is that they cannot think anyway but that is another topic which we don't discuss for some reason...
I've posted the concept about half a dozen times and got no response from either side.
