Well, if it's easier for Google to require it of everyone instead of a subset (and less risky if they should happen to miss someone who's not a "trader"), then it is entirely reasonable to blame it on the EU. Before the rule was put in place by the EU, Google didn't require it; after they did. I'm sure Google didn't go through the design, development, testing, compliance and legal analysis of deploying this requirement for the fun of it.
