Better for surveillance tech research like this to be published out in the open than developed in some secret lab. I figure these researchers are doing more positive than negative by publishing their findings. It’s not like if they didn’t publish, someone else wouldn’t come up with this and possibly use it clandestinely.
Unless you wanna run headless and do everything via SSH then desktop is better, its essentially identical to server, but with a GUI and some apps bundled by default - both of which new users and infrequent server admins generally need.
