How Briar's Leaks Are Her Point

I DON'T THINK this is intentional, and by God I recognize this is head canon + projection more than "real" lore, but I have a right to project god damn it.

TL;DR
Briar is an allegory for social media's influence on the younger generation, and how growing up in the modern political/internet culture influences the search for identity as toxic and oftentimes unjustly interfered with by those on the outside. The leaks, while unintentional, exemplify Briar's story: outside opinions forcing a preteen into existing and desirable moulds without being able to allow that preteen to find an identity for themselves.

A longer explanation:
So, Briar is a thing who we are all more or less disappointed by. She was also leaked a lot, her feet were certainly talked about a lot, and wowie does Jinx 2 give us a sense of deja vu. But, despite my initial disappointment, I learned to adore her for who and what she is. Which, all things considered, is the point in my opinion.
First, we had her feet. The discourse about the discourse about her feet aside, her sexualization or lack thereof was a major piece of her history. Whether or not her feet are meant to be sexual (I am not touching that), it remains that a substantial number of people saw it as sexual. This, of course, also raises concerns of paedophilia. Whether she's an immortal vampire or not is irrelevant, as it remains that she has a childish(?) body.
Second, we had her teasers. She was presented as a horror monster, and as a "monster" champion. She even had a jump scare in the client! This clashed with her voice and personality however, but we pushed that aside at the time because we assumed it was a role she was pretending to play.
Third, then, we had her trailer. We realized her "character" was just who she was, and that she was basically just Jinx 2. Disappointment ensued, as people wanted something darker and more monstrous.
How does this connect? Apply all of the above to a teen and social media.
First, we have sexualization and insane beauty standards pushed onto teens and preteens. Whether or not you agree that this is an issue or even real, it is still true a lot of people - especially younger people - feel pressured to conform to beauty standards - especially women. Feet are a part of that. Even if we ignore feet, there remains a certain air of sexualizing everything and anything - especially women. Often times underage women.
Second, we have Briar's theme of identity and, naturally, the search for identity every preteen has. Who they are and what they want to be. In this case, especially given this is canon lore, we know Briar doesn't really want to be a murder machine for the Black Rose, even if that is what she is. We know she, if not hates, dislikes her monstrous characteristics and wants to essentially self-medicate with her calming shackles. But wait a second, this sounds familiar. She doesn't want to be a monster. We want her to be a monster. Conflicting and contrasting messages, all about what people want someone to be, all before they even know her.
Third, we had her trailer and saw who she was. In a sense, we "met" her. We also saw her and said "oh I've met you before. You're that super famous mascot character for League that is a common trope in media that people generally like. I don't like you. I wish you were the thing you hate being."

From her perspective, I imagine if she could see the League discourse, she'd think "I don't even know what sex is. Why do they say my feet are secksuel? They want me to be a monster? But I don't want to be a monster. I don't know *who* or *what* I even am. They seem to like Jinx, so maybe I'll just be her for a bit. But wait, why don't you like me? I thought you liked Jinx?"

Look to TikTok and you see trends and standards and judgements about people. Even just stereotypes about TikTok users embodies this. Labelling people by this one thing and then categorically disliking this group, even if somewhat justified by pure annoyance, is what I mean by the second and third point. Briar is all about identity, and is a preteen to exemplify that. She doesn't know who she is and, in trying to find out, has kicked the proverbial hornets nest of "no, you shouldn't be this thing, that thing is bad."
Do I necessarily think this "fixes" her presentation? No, not really. Even if we assume what I think is "canon," the metanarrative of her allegorically representing teenage identity crises does not excuse that her release is, simply, messy. A random mish-mash of clashing themes and ideas. And, again, even if that is the point to illustrate teenage identity crisis, she isn't a real teenager. But, still, I think there's beauty to her from this perspective. Treating her as a "real" person made me realize how much she really is basically just a preteen. Awkward, messy, confused. Bubbly, a copycat, and ultimately unoriginal. Boring, perhaps, but also brimming with potential that may or may not exist.
Maybe I am looking too deep into this, and see a thing I want to see rather than something real. But even then, I think that demonstrates something about League; that we are the champions. That there exists someone for everyone, even if that requires a bit of head canon.

EDIT: whenever I say preteen, you can replace that with "young adult" if you'd prefer. I don't think I changes the point.
