It's not my problem that AT&T is selling smartphones at a rate which their infrastructure cannot support. They're compounding their problems by offering an unlimited data plan, taboot.
Encouraging users to actually use the service for which they are already paying isn't a bad thing. If this interferes with E911 calls, AT&T has a lot of explaining to do.
However, FakeSteve isn't doing anyone favors by calling it a DDoS. Is it a DDoS if everyone picks up their landline at midnight on New Years Day? Is it a DDoS when everyone goes to the post office in the week leading up to Christmas?
