Control or bust.

That ending is obviously giving into the Reapers. If it's shown what the Illusive Man wants, and he's been indoctrinated the entire friggin' series, and Starbinger is fucking daddy Reaper of a race of sentient machines that are all about subverting people's minds and influencing them to do their bidding, I'm pretty sure that's a pretty fucking stupid choice. 

"Hi, I'm a broken, PTSD ridden marine that has been dealing with the crushing weight of the entire fate of the galaxy depending on me for a solid 3 years and am finally presented with a chance to rid myself of that burden, my mind is clearly capable of controlling the machines that have been known to completely dominate the minds of organics, including asari matriarchs and this Reaper kid is telling me that I'm strong enough to do it, unlike the Illusive Man. Didn't Morinth tell me the same thing, that we could bang and not kill me because I'm special? Oh well, YOLO. I'm sure the fact I fucking touched a Reaper artifact in the Arrival DLC and was inside a dead Reaper that indoctrinated everyone that went inside it and turned them all into husks was just a coincidence, too."
