As I said, Maya is an optional love interest. You do have the choice to romance her in IS and make her romance Tatsuya in EP, but it can't really be considered canon because you're given a choice of whether or not to do it. TatsuyaxLisa and TatsuyaxJun aren't considered canon for the same reasons.

At the end of the game, the Japanese version uses "special person" which can be interpreted in both a romantic and platonic way, though I admit it's normally intepreted as the former. The wording of the English localization kinda kills the intended ambiguity, but we shouldn't consider it canon just because of that. This whole thing ties in to a series of interviews about the characters:

Q: Are his feelings towards Maya love? A: In a way, yes. Maya was Tatsuya's first love, but even so, because it happened when he was 8 years old, his feelings were more like the admiration of an older sister. Normally, time would pass and that would develop into feelings of romantic love towards other women, but in Tatsuya's case, that first love was a big sister figure that he couldn't protect, so those feelings towards Maya still trail on. Therefore, while he has special feelings for Maya, he doesn't look at her as an eligible woman. Specifically, he probably decided on his own that it would be disrespectful to date her. My feeling is that it is the most important for him to see her smiling happily nearby.

Q: Does she like Katsuya? Or does she like Tatsuya? A: That's up to the player. Since Maya represents the player, if that person likes Katsuya, then Maya likes Katsuya. And if the player prefers Tatsuya, then that means she will fall for Tatsuya. If I were Maya, I'd pick Tatsuya. But Big Brother is a really great guy...I'm sorry...you know. *laugh* But since Maya has the "big sister" mentality going on in Tsumi, if she did this and that with Tatsuya, it would be kind of awkward, but in Batsu I don't think she has that problem.

If you, the player, ship TatsuyaxMaya, then Maya likes Tatsuya back and all the hints can be interpreted in a romantic light. If you don't, then Tatsuya's love is one-sided and Maya only sees him as a friend/brother and the hints can be interpreted in a platonic light.

See? Maya liking Tatsuya back was never set in stone, so Persona World putting Tatsuya -> Maya under the "One-sided Love" entry doesn't contradict the game at all. She canonically doesn't like him in a romantic way, but as a player and fan you can still enjoy a hypothetical TatsuyaxMaya playthrough. It's like Persona 3 Portable: the male protagonist is canon, but you're still given the chance to experience a non-canon scenario where the protag is a girl.
