When you have no argument you can always play "hostility" or similar card.

You're just a liar. I use to have GrapheneOS on my phone.
Users CANNOT use any other server than GrapheneOS to sync clock using WIFI or LAN.
Why are you lying?

You can read YOUR site.

"An HTTPS connection is made to https://time.grapheneos.org/generate_204 to update the time"

You have no option to choose other server.

Your lies only confirm that GrapheneOS is not reliable.
