A reason for dropping the service wasn't provided, but as we noted when Blizzard elected to remove Twitter integration from WoW, changes to the Twitter API made earlier this year are the likely culprit. Access to the API, which had previously been free, was replaced with a far more restrictive option, while Basic access, "for hobbyists or prototypes," now goes for $100 per month. The next level up is the Pro tier, "for startups scaling their business," that goes for $5,000 per month, while the Enterprise tier, which I imagine is where a company of Sony's scale needs to be, offers different monthly subscription prices "based on usage and needs" that start at $42,000 per month.
Musk is bad at business. The biggest reason Musk is so successful is that he was born rich. Same is True for Trump.
