Including the filenames seems to have been unintentional, looks like they were logging analytics to Facebook, probably an even (form submission) but uploaded the form html with contents.

But why they need to submit that to Facebook for paying users I don't understand. The only thing I can think of is excluding active users from advertising... But is that worth the privacy intrusion?

They answered in the Twitter thread: they send data about paying users to Facebook so they can build lookalike audience targeting for new user acquisition. Other major ad platforms (Google, LinkedIn) have similar features.

This doesn’t look like the right data to be sending FB for that, though.

That’s my gripe with “if you aren’t a paying customer, you are the product” because if you pay you are still the product.

Good job, backblaze. So many years of work building goodwill with transparency in hard disk reports ruined completely with one stroke.
