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.
They also invented the transistor, C, the photovoltaic cell, radio astronomy, and … the telephone. ;)
Yes that’s the past, but AT&T labs still employs almost two thousand people. It’s very funny to try to claim AT&T isn’t a technology company and only peddles services on top of equipment made by others.
Calling AT&T a tech company because they operate technological infrastructure is like calling Spirit Airlines an aerospace technology company because they operate jet airplanes.
Are you claiming AT&T outsourced security and have contracts to back that up? Buying security equipment surely doesn’t amount to having security, that would be hilariously naïve. Equipment manufactures are not responsible for AT&T’s data security, AT&T is. There are laws around security that can hold AT&T liable, in the US and Europe and elsewhere. Whether they will hold the company liable is another question, but these laws will not accept an excuse that AT&T purchased security equipment from another company.
If they don’t have the core competency, they need to obtain it as a requirement of doing business.
