This headline is ridiculous; I expect better from Ars Technica. You "admit" to things you shouldn't have done. In this case the government compelled Apple to disclose certain data and simultaneously prohibited Apple from disclosing the disclosure. Thanks to a senator's letter, Apple is now free to disclose something that they previously wanted to disclose, about something they were forced to do in the first place.
Compare to the Reuters headline: "Governments spying on Apple, Google users through push notifications - US senator." The emphasis and agency are correctly placed on the bad actors.
