I have no love for Microsoft but I'm having a really hard time seeing how it isn't the smart default to backup the user's files/photos to the cloud. Sure, if you are here on HN then maybe you have NextCloud, Immich, Dropbox, Google Drive/Photos, etc, that you make sure to backup your pictures to. I can assure you the general public does no such thing unless it's the default in the OS.
Try consoling a few people about how the pictures or files they hold dear are gone forever and then come back and talk about this "dark pattern".
This blog post is somehow a success story? No, it's a ticking time bomb. Great, you free'd up space for email at the expense of un-protecting all his pictures/files. That's not a win.
The author gets _so close_ to the point but manages to miss it completely:
> but I suspect that he deleted files (including family photos) for which he had no other backup.
> I’m a computer nerd, and if you are reading this you probably are as well. We can change that setting ourselves without much thought, and we probably have backups of our important data in case recovery is necessary.
But they couldn't make 1 more tiny hop to "my neighbor will not manage backups and so these files are now at risk".
