I personally love IT. In fact I assumed a weak version of IT in my first play through before I read any spoilers online. However, the fact that Synthesis and Control are only available options when the player has high EMS strongly suggests that IT wasn't Bioware's original idea. The EMS requirements seem to suggest that Bioware thinks Synthesis is the "good" ending.
Not sure if you've been answered yet, but I've seen this assumption too many times without reply that I can't get it go. If this is a rehashed answer and I was already

, then move along... nothing to see here.
Now, before I get into the answer, it's nice to see someone else who suspected indoctrination on their first playthrough. It's didn't stop me from the rage quit or uninstall. However, the two days of retrospective analysis without being able to go back into the game to figure out what happen was a personal victory. Me and my Shep managed to avoid indoctrination.
First and foremost, think reverse psychology. This is just one obvious element of indoctrination. Also keep in mind how long term indoctrination is supposed to work.
Over the span of the game,
you run around trying to solve a problem that can't be fixed... oh, sorry wrong line; you gather resources, upgrades, gain allies, etc. The longer you trod through the game, the more time you are exposed to the elements of indoctrination; Reapers, husks, tech, etc. So, as your EMS goes up, your willpower and ability to resist indoctrination go down.
If you rush through the game, your EMS will be low, but your resistance to indoctrination will be high because you spent much less time running around a galaxy FULL of Reapers, husks, and Reaper tech.
The results:
Low EMS and high resistance to Indoctrination: Destroy is the only option because you cannot be fooled
Medium EMS and medium resistance to indoctrination: Control and Destroy are options because there is enough doubt created in Shep's mind that control is possible at this point. Unless the player listens to what Shep themselves say not 5 minutes before meeting starbrat. The touching Anderson chat is there to make you forget what you just told TIM about control.
High EMS and LOW resistance to indoctrination: Synthesis becomes available.
What is the kids definition of Synthesis? New DNA, Merging of synthetic and organic... sounds like what a REAPER already is. All the benefits of synthetics, none of the weaknesses of organics. It also sounds like exactly what Saren tried to convince Shep was the only solution to saving organics.
That's my take on what is available and what is not based on EMS, and the underlying impact on Shep's mental state (will power) based on time spent roaming around the galaxy.
