I will repeat, again, my position:
There is no factual information or intelligence-wise "leads" based information, or any indications, that this was terrorist related.
Because a bunch of rocket scientist self-appointed internet crash experts on APC have decided "it must be terrorism" and same group has reviewed past accidents and since "this has never happened" before, have concluded it is terrorism, does not make it so.
Again, as of now (03-26) we have no, none, zero, indications of terrorism (or suicide or similar mal-intent by people occupying the cockpit).
