The Privacy Guides website is well developed but I feel its current treatment of Calyxos is unfair.
It contributes towards pitting Open Source projects that respect and promote the privacy of the end user against each other and spreads information that is false about the operating system. I will be making a 3 pronged criticism of the Privacyguides.net stance on Calyxos.
First, the signature spoofing on Calyxos is more secure than any other implementation across all roms since it only works when using microg. No other android package other than microg and fakestore can enable signature spoofing making this feature safe and secure for the end user. This change is open sourced and can be verified on the Calyxos Gitlab.
Second, Calyxos has more user friendly privacy features than any other rom. During install the user is prompted to install a free VPN provided by Calyx, Tor and several other open source apps that add privacy to the operating system. Also, Calyxos is patched to allow the Hotspot to use the system VPN so connected devices can be secure. And lastly, Calyxos has a firewall app built in that links the system firewall settings into an easy to use application.
Third, unlike its other open source compatriots Calyxos only uses open source projects to provide its software support. Microg, Seedvault, even the browser are all open source unlike some of the compatibility features of other open source projects that offer the option to install closed sourced play services.
I hope Calyxos can be reconsidered as a suggested operating system for Privacyguides. While its not hardened like its compatriots it is more private in many ways and enables user privacy by not using Play services. It also, maintains the security model of android and is consistent with its monthly updates.
