There is already no shortage of foreign CEOs in Swiss companies. The proportion of foreigners working in the country in high-paid jobs is really high.
As for perceived disasters, I don't know where they got that idea as the Swiss economy is thriving compared to the rest of the western world right now. The last catastrophe was the bankruptcy of Swissair and that was back in 2002. Plus the company was immediately reborn as a new airline (Swiss) with very little disruption of operations. Banks have had a hard time but I don't think that this is registered in the mind of people as being a problem coming from board members. If anything ticked the balance towards a yes to this initiative, that was Daniel Vasela, ex-CEO of Novartis, receiving a 72M CHF (about 76M USD) severance package as he left the company a mere two weeks before the vote (he later declined it).
Even without laws, would others act differently around me because they were being recorded with my life record?
If reality TV has demonstrated anything, it is that being recorded 24/7 and peered at by millions of people makes you less adventurous, more respectful and more caring of others.
I think that the critics believe:  that such a large amount of money given to "neuroscience" (in quotes as it is more of a computer science than a fundamental neuroscience project) will hurt their chances to get funding in other EU and national calls (like: "hey neuroscience has its billion already, let's fund cardiology and oncology instead") and  that the project over-promises and won't deliver, ultimately hurting the credibility of the field as a whole.
I think that both concerns are grounded. The resource money is limited and as the project only get matching funds, they are currently trying to get money from national bodies. Every € that goes to the HBP will be taken from neuroscience budgets and the project if I am not mistaken plans to act as a kind of a special funding body offering fellowships and grants but it will of course push its agenda. As for over-promising, it is unfortunate that the head of the project as made quite inflated claims. He pretends that he has been misreported by journalists. You can find claims about understanding consciousness, neural coding and solving brain pathologies which obviously is going to be impossible in a decade given how much we don't know about the brain in general and about cell types other than neurons specifically.
I believe that what they receive is actually up to 0.5 B€ in matching funds, meaning that for every 1 € they get from other sources (private persons, foundations, national funding bodies, etc...), they will get another 1 € from the EU, up to 0.5 B€ for a total of about 1 B€. Also this is granted under the EU Framework Program 7 which ends soon. So really what they got so far is 54 M€ for 30 months and the rest will come after that under the new EU program/package (Horizon 2020) which is currently being negotiated. Given the financial health of EU countries right now, there is a chance that the overall envelope is cut down and it is not clear how much funds they will get from national bodies in the first place.
The EU is also funding under the same initiative another B€ project about graphene.
The Human Brain Project promises a lot (AI, curing neurodegenerative diseases, understanding the brain and consciousness, limiting animal experimentation, etc...) and it is the opinion of most neuroscientists in the US and in Europe that it won't deliver. If you google it, you will find many interviews from neuroscientists who are very critical of it. It is difficult to evaluate what really will come out of it.

Maybe they can start by not copying user data to other sites.
