Disadvantages of QR code tombstone

Hello, I would like to ask what are the shortcomings of the QR code tombstone? The disadvantage of QR code tombstone is that the information is public. As long as you scan the QR code with your smartphone, you can log in to the relevant website to understand the situation of the deceased. The information page of the website contains the life, photos, videos and eulogy of the deceased. Anyone can see the information of the deceased by scanning it, so the disadvantage of the QR code tombstone is that the information is public.
