I think it's just a poorly written title. I doubt millions of people will click on the link specifically to learn which books Portugal banned vs to learn about that Dua Lipa is doing. A better title would be "Dua Lipa opens library in Portugal for banned and censored books."
I did not get that implication. I simply thought it was a library that contains books that have been banned from some context that happens to be in Portugal.
The same people who think "banned" and "censored" books must be completely banned and censored in all places to have earned that title instead of just at one point in the past.
