TFA suggests that the previous communication on the matter stated that the account would go read-only, not that any data would be lost. Do you have any evidence that suggests other notifications were sent between? The thread you link to above says “People using anywhere from 5.??TB all the way to 152TB … got the email” but I assume that email is the one already mentioned which states large accounts are going read-only.
