Unless you have specific insider information that hasn't leaked onto the internet, we don't know anything about why Apple has moved onto their own mapping data instead of Google's data, past "their licensing agreement expired and wasn't renewed". Google might have put some crazy ridiculous demand out there that no one would take. Apple might have thrown a tantrum and pulled Google completely and said "ner ner ner". I'm not apologising for Apple, the Maps need a lot of work, but we have no clue about the internal policy and licensing negotiations that took place so we can't just assume it's out of hubris.
