Just doing their jobs, censoring the legal speech of private citizens at the request of government, after government without a shred of evidence accuses the private citizens of being foreign agents
For decades, AT&T gave the government unlimited access to all its technology. The head of AT&T and Bell Labs would personally go to DC on a secret schedule and share technical documentation that let the NSA spy (illegally) on Americans (see Idea Factory for footnotes, etc). From what I read, Twitter pushed back against the government in a thoughtful way. If you have problems with what the government is doing, use these files to file a lawsuit. If you think the US government is going to change being heavy handed I think you'll be depressed at the outcome.
The first nationwide social graph was built at AT&T Labs, made of call detail records harvested (on mag tape and possibly even punched cards at the time) from storage all over the country. It was possibly the largest database at the time. Pre-RDBMSs.
