I wish it was that simple.
Lets go for an extreme example, I'm sure it will be taken out of context but I might as well try getting the point across.
Lets pretend Apple managed to make an exclusive agreement with another large organization, like say the government. This exclusive agreement means that all voting goes through Apple's proprietary software on their fancy new iPad.
Now of course, it is your choice to disagree with how things are done and not buy the iPad...
Yes, it is an extreme example. But you don't seem to be understanding the GP's point here:
accept whatever the corporate overlords give them, or go to a corner and shutup.
It is in their best interest to trap and control you. Stop telling people to just take it!
Probably not, if you look at other incidents: http://cmeerw.org/blog/594.html it appears they just like to push the limits.
inevitably interfere with someone doing their actual job
I can attest to that. I regularly have to work around websense at work to get my job done. Most of the web use I do for work is through a backdoor. I only end up using the company network for things like reading slashdot. Seems kind of backwards. It's a big enough company that getting it turned off or getting proper access is difficult.
Websense and similar products are organizations trying to use technical measures instead of dealing with the actual problem. Employees misbehave, you have to deal with it instead of putting up random roadblocks and pretending it doesn't happen.
Maybe I didn't make it clear enough. Most of the flying car lanes you see on TV are just the layout from the ground raised up a few hundred feet. Why have the lanes limited in such a way? Why not fly over the building rather than around it? Why pack the lanes so closely together?
We can pick the analogy apart in so many ways, the point was more that by default we don't even consider the alternatives, we try to make the new just like the old.
People don't like dealing with change. Rather than trying to come up with a new system that works well considering the current realities, people try to make the current realities conform to what was previously in place.
Look at movies with flying cars, where so often the flying cars are restricted to 2d multiple lane 'roads' in the air. Seems like a ridiculous restriction to put on flying cars which would lead to almost the exact same set of problems we have with non-flying cars and traffic. It's just how people think (or is that how we don't think?)
A computer scientist is someone who fixes things that aren't broken.
