"Our hardware, our rules"?
So, just because a company pays the water bill and thus owns the water, does that mean they can lace the taps in the ladies' bathroom with contraceptives?
If the employees has signed a legally valid contract and medical waiver after being informed maybe...
Just because I own my hi-fi, does that mean I may put the speakers on the balcony, point them at the neighbours, and play it at top volume at midnight?
if you had a magical sound dampening field sure but once those soundwaves cross you property line and they enter public property or other people private property you are violating noise ordnances then no.
Just because I own a baseball bat, that means I can hit you in the head with it?
No as I have not given you permission to hit my head and you do not own my head.
Since when has the rule "the person who owns an object has total say of any actions performed by or in relation to it" ever applied to any part of society?
Ever since we had the concept of personal property? As long as you are not doing anything with it to some other person without their permission or to some other persons property, you should be able to do what ever the hell you want with it.
If you agree to a bad policy that is your problem. Don't have another job option then don't use equipment/network. There is plenty of free WIFI out there if you don't have have internet at home. Don't trust the free WIFI then use tor. You have options. The only reason I use the WIFI at work (with my personal device at that) is because I admin the network and know they have no such policy and no such logging. If they were to decide to do so I would simply comply with the policy and only use the internet for what I don't care if they see. So what if they saw my slashdot login? I only use that password for who-gives-a-shit sites with no secret information. I would not use it for banking or health-care (without a ssh proxy to my home network if such a proxying were permitted) period.
