In anticipation of Microsofts late-July hearing, global tech giants, Apple and Cisco, along Verizon and AT&T, have joined the fight, submitting court papers with arguments in support of Microsoft's opposition to US government demands to access data held overseas, according to the Associated Press.

While prosecutors describe Microsoft's position as a “dangerous impediment to the ability of law enforcement to gather evidence of criminal activity,” Verizon said the ruling “would have an enormous detrimental impact on the international business of American companies, on international relations and on privacy.” 

Lawyers for Apple and Cisco, companies that also use servers in other countries, voiced similar concerns, stating that the ruling puts “Apple and other providers in the untenable situation of being forced to violate one nations laws to comply with another.”

In its official statement, submitted last week, AT&T said the ruling would give law enforcement “a global information access tool without bounds." The Electronic Frontier Foundation, a civil liberties group, echoed the sentiment, saying the government's approach poses a "grave risk to privacy.”
