Why does owning the device not yet mean I can access the data it generates?
Opportunity
The EU Data Act applied on September 12, 2025, giving users a legal right to access all data generated by connected products in real time and in machine-readable formats. But the regulation specifies no common API shape, no authentication handshake, and no wire format that developers can build against. Car manufacturers, health device makers, and smart appliance vendors are each building proprietary implementations, or nothing at all. The second compliance phase, requiring devices to be designed for data access by default, arrives in September 2026 with no standard for what that design must look like.
Why it matters
A portability right with no shared interface is a legal entitlement with no exercisable form.
How I score the opportunity
The Opportunity Score is my own read, not a measurement: how much it hurts, how often it bites, and how little exists to solve it today. Higher means I think it is more worth building.
How much pain it causes when it shows up.
How often people actually run into it.
How little good tooling exists for it today.
More problems worth solving
Why is the software we depend on most the worst to use?
TechWhy do I still own none of the data I generate?
TechWhy can I not get a receipt proving my data was actually deleted?
TechWhy can I not know if what is running matches what my SBOM declared?
TechWhy does every C2PA provenance chain break the moment content hits social media?
TechWhy can I port my posts but not the profile platforms built from watching me?
