ATT has a rich history of being a technology company. They invented UNIX! That's in the past, fair enough.

So they used to develop cutting edge technology, they sell technology, they buy technology, they operate technology, they work with manufacturers to develop new technology, they operate the infrastructure underpinning the modern technology economy, but they aren't a technology company?

Even if you want to argue that they aren't a technology company, they sure spend enough time doing everything a technology company does to hold them accountable for their technology failures.
