The news isn't so new (https://www.lastampa.it/topnews/primo-piano/2021/03/12/news/...), but doesn't look something that will really end up well for those "barons" (no title is recognized in Italy - as should be everywhere).

However if they want the rights, they're possible legible also of having to pay to the tenants for all the improvements they did so far, and very likely taxes on the property.

So... Might end up a quite bad move.
