Great work going nowhere
"But just because it's legal doesn't mean that MVNOs will rush to disavow data sales revenue and to implement technology that puts their customers' interests above their own."
Without legislation, this is just an academic paper. Great work and a novel solution that, unfortunately, no companies, be they MVNOs or their data customers, is asking for.
It's time for governments to act in the interest of their constituents instead of their contributors. I'm not holding my breath.
