I like where your head is app but I think the game has fundamentally changed. The average attention span was lower back then and the internet specifically was almost entirely white, at least regionally. Such a app would need a massive marketing push that a open source dating app wouldn't ever be able to achieve without massive financial backing. Fedi took years to even stop being gayer twitter with no real people on it for example and there's not really women here. Dating apps are an even harder sale.
