If you read the article that was one of several things they threw out there to excuse their consistently delaying/not complying. The courts told them repeatedly that their opinions on the matter were wrong and they kept delaying over and over again.

I mean come on:

“Twitter contends that it ‘substantially complied with the [w]arrant’ because ‘there was nothing [it] could have done to comply faster’ after the court issued the February 7 order,” the court document said.
The court rejected Twitter’s “good faith” arguments, mainly because the company blew past the original deadline and repeatedly failed to raise concerns at earlier opportunities.

Twitter continued challenging the nondisclosure order and the sanctions, but the court rejected most of its arguments and ultimately affirmed the contempt sanctions, issuing its opinion on July 18.

This nonsense went on for months.
