I'm a scientist, so pretty familiar with hypothesis testing. That's why I asked Amazon why it hadn't performed its own experiments to see if they could replicate a problem that was first reported about four years ago. E.g. if the problem is due to device clock drift, as some have speculated, surely their engineers could have detected this.

I suspect the real issue is that they force the cloud account's version of which files should be on the device to override the local version's, although why this doesn't seem to be happening to devices that are not left in airplane mode for significant periods is unclear. In any case they really shouldn't be doing this to a device that can be used as a (rather expensive) external SSD, not just to read content that comes from Amazon.

And I didn't expect the IT person to give me compensation. Amazon executives were my initial contacts and I cc'ed them on all my responses. I did not ask for money or for a new device, just that they cease erasing my copyrighted content from a device I own.

Far from being unhelpful, I explained the situation in detail, provided a list of the deleted documents, including file types and approximate restoration dates from last year prior to the latest wipe, generated and uploaded device log files, and pointed the company to numerous other accounts of this happening when they claimed I was the only Kindle owner to have reported it.

My initial contact with Amazon about this issue was in mid-December last year. Had they added non-Amazon content to a Paperwhite back then, taken it offline for the next few months, and then synced it, they could well have seen that I was not hallucinating. The fact that they didn't tells me they either already know what's going on and don't want to change it, or that they just don't care. In either case I won't be buying any new Kindles or content from them any time soon.
