I use Linux as a workstation OS. Am I doing something wrong?

You can prevent users from getting root access.

Linux is frequently used by ordinary users.

And because Linux boasts with "BIC" and "CUBIC", some users think 
themselves to be network experts.

My aim is that we eventually obey standards and don't abuse ordinary 
workstations as harmful network experimental equipment.

(When I was Transport AD I actually really tried to get CUBIC, C-TCP and H-TCP to published as Experimental RFCs, like Highspeed was. But it seemed like the authors never actually cared enough to move the work from the IRTF to the IETF.)
