We need to define when a theme can be said to be in a story or story event. My take on it is that a theme exists if it's evoked by certain elements in the story and is not specifically denied or contradicted.
Invoked according to a certain interpretation that is solely on you. And also denied by further developments in the games themselves.
Like I said, the Reapers ceased being mecha-Cthulu the moment we started killing'em and making'em (ends of ME1 and ME2) and the final nail came when they turned out to be mere killbots in service to a holographic child. Reaper tech was never "we're not meant to know" (I've only ever heard you claim that) it was just avoided like the plague, because like the plague, it ruined your day 99% of the time.
Destroy is thematically anti-synthetic because of the Catalyst's rationale combined with the fact that you do destroy all synthetics. It's also supported by Javik. It doesn't matter whether you believe the Catalyst's rationale is stupid, it doesn't matter if you personally choose Destroy for other reasons, the theme is still in the decision.
That rationale
is the only reason you destroy all synthetics. It's forced on you, as a consequence, of the decision, not as its main effect. A side effect cannot carry a theme. That's like saying killing the Shiala clones in the Thorian fight makes you anti-cloning. It really doesn't. It just had to be done (and I really mean that here, unlike in Destroy, where it's arbitrary nonsense).
It's different from Synthesis because in Synthesis you're a) accepting the holokid's bull**** as true and

your decision is necessarily a direct response to it. Destroy and Control barely acknowledge the holokid's babble. Synthesis holds it as true and responds by removing the offending distinction. That's a main effect. That actually can't be ignored. But all synthetics dying when we were only trying to kill our enemies? Tragic, but incidental. It's not a theme, it's collateral damage.
And Javik may anti-synthetic but he's only one character on the squad and no more significant to the final choice than Legion or EDI (or even Tali by the end of the Rannoch arc). I don't see why his opinion should be held above the others' or why it should be more significant to a particular ending than the others' would.
