I was a pretty early user of dropbox. One of things I used dropbox for was storing some of my college homework assignments.

I estimate that these assignments occupied ~10 megabytes at most.

Dropbox deleted my stored files due to account inactivity. Yes, they sent me an email (to a email I do not actively monitor anymore) saying they would do so.

Storing 2GB worth of files on S3 Glacier for 20 years would have cost dropbox less than 2 dollars.

They lost me as a customer for life, and do not deserve sympathy.
