The fact that we're posting in this particular thread means that all of us are going to have an extremely skewed view of the fandom/fan reception, but Remake sold like 7 million copies....how many of those millions of players actually give a shit about any of this? (I mean shipping in particular, waifu wars are a different story). Not to give SE too much credit here, but just because there's also a loud, vocal minority of flat-earthers online doesn't mean that science is in its flop era.
Shouldn't the fact that there aren't any other love triangles in mainline Final Fantasies prove that there isn't a real love triangle in this game?
FF7 is the only FF with a "love triangle" because FF7 is the only game where the protagonist has a identity crisis in which he's literally pretending to be a different person for half the game.
A typical rom-com love triangle is this: girl is attracted to two very different boys who bring out different sides of her personality. (Let's say one is a wealthy businessman with a heart of gold, one is a struggling artist who challenges her creatively). Both are valid options, but stories demand resolution, so eventually she must choose one.
This is a vast oversimplification, but here is the "love triangle" setup in FF7: Boy is attracted to two girls; one girl is initially attracted to him because of the fantasy/delusion he's projecting; one girl is literally the only person on the planet who knows his true self.
Or from Aerith's perspective: girl is attracted to two boys; one boy is her first love who dies trying to return to her (though she doesn't know this); one boy she's attracted to because he reminds her so much of her first love (since that's literally the man he's pretending to be).
There's no real love triangle in either of these situations, no real choice to be made, because your protagonists are never going to end the story choosing a fantasy/delusion vs. the real thing. The "love triangle" is resolved when Cloud's identity crisis is resolved, (and I don't see hundreds of pages of people debating whether or not Cloud was actually a First Class SOLDIER).
Obviously, SE will play into this because it's great dramatic tension, creates juicy conflict (and you're gonna need lots of conflict for three 40+ hr games), but again, narratively speaking, there is only one possible resolution for this.
I don't know what else you can ask them to do? There are always going to be people who interpret Cloud and Aerith's relationship romantically because Aerith is (at least initially) romantically attracted to Cloud. Every single interaction between them is going to be read with a romantic lens by some people, so what is SE gonna do? Just not have them interact? Even that won't stop some people. I legitmately think they could make part 3 an M-rated game where Cloud and Tifa go through every position of the Kama Sutra and there are still gonna be people who think that he's secretly thinking about Aerith the whole time.
Obviously SE is not going to make that game because they want to tell a broadly appealing, good story that will sell lots of copies. But by that same logic, they're not going to undermine their own storytelling just to tell off some shippers. Let people ship whatever the fuck they want, but the story is what it's alway been since 1997.
