That's a nice ethos to adopt as a government, but he can't ignore the crippling taxes his government have instated since taking up office. I feel very sorry for business owners in France at the moment.
Open data and open source encourage the commons and sharing. Taxes goal is to have everyone contribute to common good. I see more of an alignment than a contradiction. Remember that taxes are poured back in public transportation, hospitals, social security, etc. (Not measured by PIB). Also remember that what you read about in the media is biased by those that are unhappy.
