The more I see, the more convinced I am that Silicon Valley was actually a documentary.

A fraudster, a terrorist, a money launderer, a drug dealer, a pedophile—these are actually a huge audience for whom the IT industry can release separate versions of the operating system and hardware. And that audience will pay for it. For the vast majority of ordinary people who consume IT benefits for free (being a commodity themselves), it makes sense to use controlled products.

It doesn't have to be controlled in such a way that it produces monopolies or enables surveillance.

Local chats are saying that this is retaliation by a drug cartel after a 10-ton shipment of drugs was intercepted - this was reported in the news recently. In general, Spain has a long history of railway attacks carried out for mafia-linked, pseudo-political reasons.
