Yandere-Dev must know that most people have figured that she must be the daughter of the Journelist; it makes sense given what little we know about her. Like the Journelist she is good at finding information about people and must good at stalking to find it without being seen. In the tapes, the Journelist mentions his daughter get's a lot of money from somewhere, spends a lot of time on her computer and might be involved in something dangerous (blood on her clothing). In the old opening she even tells Yandere-chan that she's training to be an investigating journelist when she leaves school (though that information is outdated and not canon). If she truly was the Journelist's daughter that would give her plenty of motive to keep an eye on Yandere chan. If she listened to the tapes she would know about how dangerous Ryoba Aishi is and if she saw her daughter mimicing her behaviour, of course it be best to stay in her good books and gather whatever information she can on her.

If she does 'betray' Yandere-chan, maybe she's getting revenge on Yan-chan's mother for what did to her father, believing it to be the main cause for her miserable home-life. Or maybe she doesn't even care about her father (honestly, why should she?) and is just she's trying to prove herself to be better investigator than he ever was.

However, Yandere Dev said on twitter that Info-chan's motivations are "a major plot twist that he doesn't want to spoil" and he makes an effort not to put anything important to the story online. So I'm thinking maybe Info-chan doesn't have a direct link to the Journelist at all (though being Info-chan she likely knows about the history about him and Ryoba Aishi) and it could be a red herring. Maybe the Journelist's daughter is someone we haven't met yet? Maybe even a future rival?
