"It's just your opinion" is usually what people say when they've run out of actual arguments but still want the last word.
JRPG isn't a synonym for turn-based game made anywhere on Earth. If it were, we might as well throw Baldur's Gate 3, Divinity, and half of western RPG history into the same bucket and call it a day. There are design traditions, pacing, narrative structure, and cultural roots involved.
And the indie label also isn't a vibes-based aesthetic choice. Once you've got a major publisher (Kepler Interactive), a sizeable team, full VO, cinematic presentation, and production values clearly aimed way above the small-scale indie space, calling it indie becomes more of a marketing fantasy than a useful classification.
