This prohibition of freely using all available data will create great arbitrage opportunity for the shadow economy, and will have a net negative effect on innovation.
I think prohibition has very bad side effects, and that MORE transparency is the way forward in politics, economy, and also society. This includes allowing businesses to use all the data they can get their hands on. People can produce infinitely more data than any google can realistically process.
I cannot understand why people who are otherwise for transparency and against prohibition are celebrating this as a big win against FB/AMZ/GOOG, as those players can easily shell out another $10M here and there to be compliant with this regulatory monster.
