Could the Benefactor Be a Shadowbroker?

I thought it was mentioned in the LOTSB DLC that the Yahg shadow broker killed his predecessor cause he was treated like a pet.  When Liara assumed that the Yahg got really angry so I am assuming that she was spot on.  

My thoughts about the Benefactor, it's a large galaxy and there are other groups that have enough funds and political will to fund and push the andromeda initiative.  Doesnt even have to be human.  Although so far the major storylines have been human focused.  Anything is possible but I feel that the natural progression of the story would favor having the Benefactor in Andromeda(not far far away in the milky way.  (Unless they botched the storyline and gave up half way like the whole dark energy thing on Haestrom).  If I am writing a commercially viable story, I would want to create another Illusive Man type character that will haunt and plague Andromeda for MEA2 MEA3 until the story ends. I wont be writing about someone back in the milky way that has almost no influence or presence in andromeda.  So using this as an assumption, by means of process of elimination, it wont be the shadow broker nor the illusive man, they could be involved in the foundation but they are not the benefactor(if the benefactor in fact is a person and not an organisation/entity). Also found a little note in a kett base, so if this is indeed from the same benefactor and not someone that did Hztch a favor, then this would indicate The Benefactor is indeed in Andromeda having success on EOS, pulling strings behind the scenes(maybe staying out of people's grief? LOL).  Advent seems like another org that we know little of and also living on EOS. I would see the Benefactor as someone very similar to Reyes in terms of his mode of operations but on a much larger scale.
