The digital single market strategy “in no way” aims to limit the progress of U.S. tech firms in Europe, Mr. Ansip told The Wall Street Journal.
No worries there !
The European strategy is always to have more and complicated rules (VAT got far more complex by Jan 1st 2015, net-neutrality is discussed, data roaming is under attack, etc).
European politicians do not understand that all the big companies once started as very small companies.
By complicating things (again: VAT, data roaming, etc) the entry levels are raised.
By the time successful US companies (soon to be Chinese companies ?!) reach Europe they have enough muscle to adapt to the rules.
Small local companies hardly ever grow that big. And it will only get more difficult.
