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.
