I wonder. In my opinion more rules only means bigger hurdles for newcomers. The big companies might have a setback but will survive one way or another because they have the knowledge and money (lawyers, lobbyists) to adapt.
A good example is the VAT law of Europe. No problem for big companies, but small companies struggle to comply (its a returning subject on HN). Or the net neutrality law in the US: it will become harder for a startup to disrupt YouTube.
Europe is too concerned wrestling with large US tech companies to understand that more regulations will only exacerbate the very thing they are trying to get away from.
