If the mandate (whether by regulatory or insurer/market force - we’ve established that the providers don’t want any kind of standardisation or data transfer, the hypothetical I’m proposing is that they’re dragged into doing it) is that they have to put their data into some data broker, if they want to keep their own copies too then the cost of doing that is their problem (or a calculation that the value outweighs the cost). In an ideal market, another player who didn’t want to hoard data could undercut them (not having that cost). Tuning either the cost/benefit of outsourcing or the nature of the incentives, I suppose, are the key.
