Kdeconnect is very cool but also pretty sensitive. There are many reasons why people would like to turn it off.
I already tried placing an empty autostart file with the same name in ~/.local/share/applications/ (same with discovernotifier) and this didnt do anything.
Another option would be simply closing the firewall (which will be done by default) but I think this doesnt affect bluetooth?
There is a hacky way of converting it to a systemd service
First, move /etc/xdg/autostart/org.kde.kdeconnect.daemon.desktop out of that autostart dir and make sure KDE Connect is not started (possibly kill it). Keep in mind that this file will come back if you reinstall or upgrade the package.
Then copy the file to ~/.config/systemd/user/ and do
# One time so systemd picks up the new file:
systemctl --user daemon-reload
# to start/stop:
systemctl --user start kdeconnect.service
systemctl --user stop kdeconnect.service
# to enable, which means it is started automatically when you login (and killed when you logout. The --now part also starts/stops it right away
systemctl --user enable --now kdeconnect.service
# and disable
systemctl --user disable --now kdeconnect.service
# output status and log (add e.g. -n 30, if you want to have more log lines)
systemctl --user status kdeconnect.service
Uninstalling is not an option, as on Fedora Atomic desktops users cant reinstall apps that were uninstalled in the image building process.
I am planning a uBlue variant with enhanced security and need to fix this issue. Especially using it via bluetooth is great, but of course also attack surface.
Other requests
This will for sure come up when making something compatible with only systemd.
Even though this should also be very possible to implement in sysvinit etc.
