While ProtonVPN has already released Windows and Android versions, according to Dr. Andy Yen, CEO of ProtonMail, their reason for releasing the free macOS version "is to make the world a safer place by ensuring that citizens around the world have access to an Internet free of spying and censorship. Releasing a free VPN service for macOS is another important step in that direction.”
