So, yes, if you see the Geth as good, you'd go out of your way to save them.
Just one example... but there is a lot wrong with the ending, I'm really not seeing the point this is one of them.
You just described what's so objectionable about the ending in the first line of your post. The space-god was clearly, profoundly, and demonstrably wrong
; but the player is forced to ruin the status quo in one of three similar ways as if he has been thoroughly convinced that the kid is right
. This is contrary to every lesson the events of the Mass Effect trilogy has taught him. Geth and Quarians live in peace. EDI is just as human as Joker. Shepard is neither organic nor synthetic, and it doesn't matter. The theme of the game up until that moment is that synthetic or organic 'meat' is irrelevant; only the mind or 'soul' of a sentient life form matters.
Since organics will fight organics (rachni, krogan; turian, human) and synthetics will fight synthetics (true geth, geth heretics, reapers); and plenty of species will engage in civil wars amongst themselves; the special wonderful green ending of unification-through-biology means absolutely nothing. Congratulations, Shepard just gave everyone glowing blue eyes and vaginas made of skin. He hasn't changed their culture or philosophical motivations, so future wars remain inevitable. They're still disparate societies of people; the only difference is that they now all bleed the same colour. So all he's done is make a cosmetic physical change and ruined the mass relays. And he fucking knows this, because of the three games we just played. So the ending makes no sense.
Shepard has proven the geth - and synthetics in general - deserve life just as much as anyone, so the red ending is just as bad. It only makes sense if we get a big reveal at the end that it is necessary to cut off a finger to save a hand, or that it was a test to see if he could make the choice to save the galaxy by sacrificing himself and all other synthetic life. Which is why it would be really nice if the test was all in his mind, and killing the reapers simply meant he'd broken their control so he could fuck them up for real without sacrificing EDI and the geth.
The blue ending is the only ethical choice which jives with the logic of the rest of the game. Control the reapers and save everyone. But since we're constantly told that this is impossible, and since there's no real confirmation that this is the best call, it seems like a weird thing for Shepard to do, because - as we already know - he has no reason to choose any of the three paths, since all his experience up to that point disproves what he's being told. Control the reapers, hope it works, and destroy the mass relays. It's the best of a bad bunch, with only the words of an illogical, genocidal space-god to suggest it will even prove successful.
It's unforgivable that players can't argue
with the space-god - success dependent on war assets - and persuade him that he can just call off the reapers; because Shepard's influence over galactic politics and culture has successfully demonstrated that there is no further need for culling. There is peace between synthetics and organics and strength in galactic diversity; and I'm not racist but my pilot is actually hooking up with a synthetic, so there you go...so seriously dude, just stop murdering everybody and see what happens. You can harvest organics in a horrifically violent and traumatic way in a few thousand years if I'm wrong. But right now, everything is pretty sweet, and I'd like to go home and party with my crew without wiping out a species or destroying the means by which this diverse armada you see before you found each other, and united in the hopes of being able to live to enjoy their newfound peace.
...You know, the galactic peace that I worked for something like 200 hours to achieve; that you just ripped away in a lobotomized ending penned by your Battlestar Galactica-obsessed offspring on Bring Your Least Talanted Child To Work And Have Them Fuck Up The Ending To A Trilogy That Spanned a Generation Day, Bioware.
