The writer uses the terms "locked out" and "frozen", but also says that she is not allowed to share documents any longer and maybe unable to access her documents from a tablet and a phone, but perhaps still from a laptop? (The article reads like a fucken drama piece instead of... you know... actual journalism).
If she has any type of access, it seems like it is very easy to fix permanently:
Download documents.
Register a domain.
Get a hosted Wordpress or some other foolproof CMS.
Put documents there.
Don't rely on a free service for something that has value you.
