We do tech. There are more startups on my city (which is small) than what the article is mentioning as average. The article assumes that "doing tech" needs to be something like a facebook or google and sell customer data like there is no tomorrow. It's a bit different around here, we like it that way.
Europe can do tech but they don't really make it an important target. Also many of the good people in tech choose to go Silicon Valley (which is now ~60% foreigners) so this depletes the pool of EU talent. The bigger SV gets, the harder it is for person in tech to resist the temptation to go, and for local EU startups to find the proper resources.
And the EU doesn't yet act like a single body with a unified strategy when it comes to developing the tech sector, unlike the US or China. It's hard to mount an offence against an already established leader when everybody is pulling in another direction.
