I suspect the potential for abuse is the reason they’ve walked back. The problem is that data will be private and the gatekeepers are the ones who stand to profit. So you’ll have another situation like those ad companies who underplay bot impressions
Which is literally _next quarter_ and retroactively applies to all current games. That's _really soon_, and is going to cause headaches for any publisher/developer looking to release soon.
Eh, yeah. Once had a service provider promise their new API would “easily” handle our needs (I still remember the tone the sales rep used every time he said easily; it so reliably came out sounding the same every time, it seemed practiced).
3 months of integration dev later, we start load testing, the external API fails spectacularly. They tell us to redesign to use their old batch API 35 days before our deadline. We tried, failed, ate shit with our customers. Provider was too big to pick a fight with. Startup failed.
I wonder how they will figure that out. It is not trivial. And if they don't disclose how they are doing it, it has a large potential for abuse.
