This is the EU. Like most governments, if they thought they could get away with it they would not just outlaw Tech Giants, they would outlaw the internet itself, along with any source of information that they cannot easily sue out of existence. Hell, they would outlaw people talking to each other without permission.
It was worst with Jose Manuel Barroso at the head of the EU commission, who needed to hide ... well, why don't I just say it. He spent a big part of his youth being a violent communist protestor (he wasn't even a now-fashionable Marxist, he was a Maoist. He protested IN FAVOR OF the "cultural revolution" in China, in favor of the killing of between 80 and 300 million people. He was explicitly anti-Marx, though I don't understand why), and has more than a few convictions and arrests for destruction of property, beating up people, assault, ...
Frankly, he is THE stereotype of what is wrong with leftists. Turns out, surprise! It's not about communism, or rights, or ... At least, it isn't for him. He was offered power through what, though people don't often think of them this way, is one of THE most capitalist institutions on this planet, the EU commission (used to be named "The European Union of Coal and Steel producers", and hasn't forgotten). He of course, immediately and totally forgot his "conviction" and took the power (of course there were many steps in his rise to power, but ...). For Barroso leftism was, and presumably is, nothing but a way to amass power, to maximize what he accidentally got thrown into at university.
But the worst of it is, he is a suspect in an unsolved murder. Now that isn't QUITE as bad as that sentence makes it sound, but close. At one of the protests where he was, someone was murdered, and the police knows he was in the group where the death occurred. Hence, he is a suspect. Along with ~20 others. The murder was "never solved".
There's even more than a few reasons this information is hidden. First is that he's involved (as well as another famous Portugese politician). Second is that the police essentially let the murder go, and "that this might lead to copycat ...". Frankly, that second part is a genuine concern.
