This happens all over the place -- for some reason, the majority of the people won't learn. They'll tell you horror stories about how they lost a lot of work (or even money!) because a provider never gave them support, yet, go back to that same provider.

A group of acquaintances had a Facebook group where they shared research and documents. It got deleted and they lost everything. Thrice. I suggested they used something else for document storage each time, but was just ignored or shooed off.

The root cause of the problem is kinda beyond me -- but it's clear that people are unwilling to learn from experience when it comes to these things, and that these free services will continue to behave as they do because there's no downside to doing so.
