Twilio, a cloud communications company, is defending user privacy by supporting Microsoft's challenge to blanket nondisclosure orders issued by government agencies when requesting user information. These orders bar companies from notifying users of data requests and can be issued for an unlimited time without proof. Twilio has filed an amicus brief in support of Microsoft's position, along with other tech companies, emphasizing the importance of trust and transparency in business relationships. As a cloud communications company, Twilio believes that trust and transparency should prevail over nondisclosure orders, and it issues semi-annual reports documenting government requests for information received by Twilio.
