I'm quite happy to express an opinion that is widely held by people in a country where many English speaking North Americans move to using jure sanguinis passports. If you move to the UK using Italian jure sanguinis I wouldn't tell anyone how you got in because the majority of people of all stripes would disapprove. That is the truth, that is the national mood in 2016, and people deserve to hear it. You have plenty of Americans cheering you on, so why not see the counterargument from a place that many intend on moving to?

Imagine if you went on a subreddit for tax dodging. Yes, there are many legal schemes, but it's not fair. If somebody was helping others to legally weasel around the law you might be inclined to comment that you found it distasteful. Just because it's a law doesn't make it fair. British people tend to take a hard line when things are seen as unfair.

People with British grandparents can't live here, but you can. Graduates who studied at our universities can't live here, but you can. Husbands and wives of our citizens who make less than £18,500 can't live here, but you can. Skilled immigrants who make less than £35,000 can't live here after five years, but you can. All because you had an Italian grandparent, whether or not you have any connection to this continent makes no difference.

I really don't see how the fairness of this situation is debatable, regardless of legality, and potential expats deserve to know that there is a very strong mood against this way of immigrating. By all means use this law to move to Italy. Help improve the country and explore Europe. Then maybe move somewhere else. Earn your stripes like every other immigrant. But don't just get an Italian passport so you can move to a different EU country.
