No default gnome app will be able to toggle that default. You can hack it in gsettings.
And worse, the fact there is a setting means that only the default will be tested. The feature will slowly but surely bitrot. In a few years we’ll see a proposal to remove it entirely. This is how software development works.
This is just incorrect, sorry to break the news. Most modern electric cars are hardwired to phone home. In most models the surveillance is fused directly into critical components like the fuel pump or the braking system. You cannot just pull out some wires in the dashboard. If you disconnected these things the car is unlikely to work. These details have been covered by people who have worked in the industry
As I explained elsewhere there is no official app to change this setting. Users can hack their gsettings.
Support for middle-paste will slowly but surely bitrot and eventually be removed.
