The assumptions being made about him killing himself are vast. First you have to assume he had some serious mental health crisis without evidence, or that some other dark secret was about to be revealed about him, or any number of other assumptions without evidence as to why he might have been motivated to take his own life.
Therefore the least amount of assumptions one could make was the obvious: He was murdered to silence him while he was a key witness against a multi-billion dollar corporation trying to get out of being held responsible for the deaths of other people they already killed.
Basically what Egon said below.

I think they mean "assumptions" in general - like what is defined as being an "assumption" wrt Occam's razor?
