There's something better than a free market: a competitive market. Multiple roughly equal providers competing on price, features, quality and so on benefit consumers more than the philosophical free market. But it's not in a com

There is plenty of good work on anonymising and fuzzing location data. But unfortunately the results show that the amount of fuzzing required for anonymity is huge. "Hours and 100m" are far from enough, only something like "y

It's understandable that being up-to-date with the latest academic results doesn't guarantee success. There are many, many other factors that determine the eventual success of a startup, and therefore it's investment appeal.
