Click bait.

What I describe below applies to APFS sparse disk images only — ordinary APFS volumes (e.g. your SSD startup disk) are not affected by this problem. While the underlying problem here is very serious, this is not likely to be a widespread problem, and will be most applicable to a small subset of backups. Disk images are not used for most backup task activity, they are generally only applicable when making backups to network volumes. If you make backups to network volumes, read on to learn more.

The title clearly qualifies the claim: "MacOS may lose data _on APFS-formatted disk images_"

I didn't know there were APFS-formatted disk images (new in 10.13). Even when you consider the many different kinds of disk images that macOS supports, there's a pretty clear distinction between disk image and a backup of your startup disk, made to another partition in another drive.

Any additional clarification would get into "MacOS may lose data on APFS-formatted disk images (disk images, not disk-to-disk, as in another volume..." territory.

A lot of people do make backups to disk images though, especially techies. I believe that remains the only method to use 'time machine' with a generic network connected device rather than an apple branded 'time machine' device? The last place you want an unreliable file system is your backups!

Exactly. But the Apple Apologists, who are just doing their job, will say "#FakeNews" or "but Windows!" or anything to deflect from the terrible problems that platform is having.

Yeah this is the opposite of a click-bait title; it clearly explains what the article is about.

"may" lose data on "APFS-formatted" disk images.

Yes, fairly limited impact, but still. Data loss is fucking important. We aren't talking about an occasional stutter when moving windows or a sound driver that sometimes needs a reboot to resume working. This is a major bug. I would really really like it if Apple would get their shit together so that people who actually rely on their computers to work correctly can upgrade at some point.

You appear to have an agenda of protecting Apple.

The title is very clear, and the first paragraph which you quoted explains it in detail.

It's significant that an established respected company--the makers of Carbon Copy Cloner--will not support APFS formatted disk images for its backups.

While your agenda may be driven by the need to protect Apple, the rest of us need to know this important news about APFS so we can be fully informed.
