They may not have the source code anymore if it's that old. Modern mainframes have continued to evolve and a recompile might be necessary. It's actually not that hard to believe that the source code might be missing, in that era the source code was usually punched out on cards which had to be physically maintained in boxes which could easily be lost.

Get a white noise generator. I have an ancient one that sits in the corner of my office. It helps drown out the background chit chat and definitely helps me focus my attention without distraction. No one notices that is is on but if I ever turn it off you suddenly become aware of just how noisy everyone is, you can hear every sniffle and word spoken and you realize just how distracting that really is. Maybe stage such a demo, have your noise generator running for a couple of weeks, then one day when your boss is in your cube, just reach over casually and turn it off. When he suddenly becomes aware of all the distracting chit chat pouring in, point out how much more productive you have been since you got the white noise generator and how it serves the same purpose for you music used to do when it was allowed. It might open his mind a little. Or not. But the main thing is you can concentrate.

This doesn't sound like a bug or leak, more like some users set up links or otherwise made their messages public.

Same reason so many people use the crappy msn email accounts that come with their crappy msn internet connection. They don't know any better and since it's microsoft - it must be good enough. Microsoft dosen't need the smarter than average half of the bell curve to use their products, they only need a certain market share and they'll make buckets of money.

There is still no need to prohibit, rather educate and if necessary medically rehabilitate. Locking people up for addiction rather than helping them cope is not cheap, but it's still cheaper than housing them (in prison) for many years or even the rest of their lives. Many have lived out quite productive lives while nevertheless addicted to drugs like cocaine and heroin. Opiate additions do not really harm the organism until the supply is cut. I'm not saying it's great to be hooked on opiates, but there's no legitimate reason to favor criminal incarceration of an opiate addict vs. building a counseling and treatment network designed to build skillful means so that an addict can managing their use intelligently.

Legal drugs would allows you to pay for a nanny fee by participating in a professional setting.

All drugs have a context for use that doesn't automatically put bystanders at risk. Clearly if you're going to do PCP you shouldn't get behind the wheel until it is safe to do so, several hours later. Provided guided and smart contexts where drug use can be matched with a responsible setting can eliminate these side effects. If you could go somewhere safe and guided to trip on LSD for 10 hours, be fed, spend time to reflect and consider your experience, it might be very interesting. You might be less likely to drop some acid and get behind the wheel and go look at the pretty lights and end up in the ditch wondering what happened.

This is a myopic POV. Imagine, if people were holding their breath until they passed out while driving people would die as a result, sure. But people don't do that. Create a context where smart drug use is allowed without the need for the furtive criminality, you can go somewhere safe, use, trip, sleep, whatever you need. You don't have to get behind the wheel. The reason people are driving around stoned on drugs is because we haven't funneled them into a constructive drug use pattern since it's illegal to do so. A supportive drug use setting removes much of the cultural and circumstantial reasons for the harm. No one really wants to combine doing drugs with driving, but they are forced to drive and do stupid stuff because we haven't provided smart conscious and innovative alternatives.

I am willing to bet that people pay more to house and prosecute numberless drug users/sellers than it would cost to provide social services to help them cope when their usage becomes a detriment to sustaining themselves in the context of their other decisions. Not everyone has the same responsibilities. If you have a wife and kids and a mortgage and a bunch of bills it hurts you more to be an addict. If you live in a cheap apartment and live off your investments, what's the difference if you chose to live your life stoned out of your mind.
