What a sad press release, I am sure people at their corporate office were sweating over this. The long and short of it is that users trusted the service would work and had possibly a great deal invested only to get a comment when everything breaks down deflecting blame "OMG we weren't prepared for what our users did!"
We live in a sad state of software. I expect things like this and the Equifax scandal to continue if things like software security, reliability, and performance aren't taken into account.
