Ad someone who goes to Canada every two months in the last 15yrs, I had witnessed the regression not only in the liberties, but also mood of the people. No one would have guessed a decade ago how a country with so much potential and human capital would had become in this state! I would not only blame the Liberal party though… it is something bigger than them, same in the US… and most of the West.
I hear you, I am worry too. But again… this is a risk at the European level, not at the Spanish one; in Spain, it simply would not pass today. with a different government, of course, it can… Of all freedoms, this one concerns me the least, simply because it is mostly impossible to enforce for citizens.
Back to the original question though, of the 8 requirements, this one on privacy we could leave as a contentious point. But it is because law, it will affect all EU contenders ( and Switzerland will be pressured to oblige too soon after)
