AT&T made 120.74 billion in 2022. They can afford a lot of bad code.

Revenue is not profit.

Edit: Jesus. Their profit was $70b in FY 2022?! On $120b in revenue? Maybe I’m the one misunderstanding.

“60,000 people lost full phone service, half of AT&T's network was down, and 500 airline flights were delayed”

I'm sure AT&T care about that due to their humanitarian nature.

AT&T is not humanitarian non-profit company. It should worry about increasing its profits by providing people with good product so that people choose them over competition.

That hasn't seemed to be their overall strategy considering how shitty their service is.

I personally had better experience with them than Verizon. But whatever. The fact that they have customers today does meant that they provide competitive service. Today, you can easily switch provider.

AT&T does a lot more than provide phone service.

It is still a provider.

Okay? And?

I can ask the same about your post. My point is that you can change it.

Which would matter if that was AT&T's only source of revenue. Now tell me how you can change ISPs from AT&T easily. Especially in a smaller city or town.

Natural monopoly and anti-competitive behavior would like to have a little chat with you in that dark alley over there...

Yes, anti-monopoly laws are important to provide competitive market.
