Too little too late.
I was in Florence in the mid 80s. It was a beautiful ancient Tuscan city, with plenty of tourists, but it seemed authentic.
I went again last year, and vast areas have turned into a glitzy shopping mall, with many international brands represented. (Also, so many leather goods shops.) It looks like the same disease that affects Prague: popularity has attracted high-end commerce and changed the city completely, destroying the original character.
Key boxes aren’t the problem.
