Walu, 

Good writing. However, there is need to separate FOI from " Re - use of public sector information " by third parties. FOI emphasis is mainly on information to ordinary citizens so that they can effectively participate in their governance. "Re-use" is more about commercialization of public sector information by third parties as your Google example shows. A policy framework for the latter is also important as it opens doors for new "Information" industries powered by innovatively re-packaging information held by government to meet specific social-economic needs
