Because a technology is created after spending millions of money and years of time.
But whether that technology can be commercially employable is unknown to the technology creators.
For commercial viability a technology needs to be employed in a big market with high population and high purchasing power. Only then there is maximum chance that the technology can be employable & invested money will return & may be with profit.
European companies have small domestic economy with high purchasing power but low population.
So the best option for them is to sell their technologies to USA and now to China and earn a good profit covering the cost.
USSR also had same problem with USA since 1974 Nixon Breznev Deal. USSR was highest patent holder and creator of latest technologies. But USSR had to sell their technologies to USA which had three times higher purchasing power. That was an important reason why Socialist Block failed to gain handsomely from opening up of Breznev Era. This was well observed in Perestroika by Gorbachev.
