Not always. If someone really wanted to, it’s easy to create aan in the middle attack with something like a VPN. Shouldnt really ever trust public wifi with sensitive info. Can easily be sniffed with a little effort

ddg relies on Bing so it isn’t really comparable, idk about kagi’s costs but they claim 1.2 cent per search and an average of 700 searches per month (as what they are serving and hence pricing for)

I’ve been using Linux (and UNIX) professionally since the kernel version started with a “1.” I have no need to try to prove anything to you. Linux has installers other than just those invoked by a package manager, and it is laughable that you claim otherwise.

Systemd “enabled” services are literal symlinks… whenever a target runs, it tries to start also all the service files on its “wants” directory.

You can literally enable any service for next boot by making a symlink in /etc/systemd/system/multi-user.target.wants/ (or whichever other target you want it to run on) as root (and installation scripts are run as root).

ln -s /usr/lib/systemd/system/whatever.service  /etc/systemd/system/multi-user.target.wants/whatever.service

OK… challenge accepted. Maybe you don’t know about systemd user services.

Content of myscript.sh:

$ cat ~/bin/myscript.sh
#!/usr/bin/env bash

while true
do
    now=$(date)
    me=$(whoami)
    echo "User $me at $now"
    sleep 10
done

Now run the script (mytrojan.sh) and check service status after that:

$ ./mytrojan.sh

Reloading systemd for the user
Enabling and starting the service
$ systemctl --user status my_test_service.service

bruh a unit file can be written to the system or to the user profile

systemctl --user enable name.service

And i can most certainly write bash, and do write bash scripts, that write unit files to both user and system profiles.

Maybe you dont know what your talkign about. just because most install scripts don’t include enabling the unit file for the system, doesn’t mean they can’t.
