What everyone says about MS being a big dog may be true, people in the hacker community want their names on the big board as "the one" who fed the dog lemons. I've seen and heard every possible argument about MS and their "evil" ways, but am convinced that they are a business like any other. They push their products hard and work very hard at marketing them.
The Justice Department can work at making them walk the straight and narrow. That has nothing to do with the technical soundnes or weakness of 2000. I like Win 2k and think they have surpassed 4.0 by light years with the product. I think that the capability to "harden" the OS is a lot stronger than with NT 4.0. They have done a good job.
The reality is that no matter who was on top, be it Sun, Novell, HP or MS they would be attacked, because they were the "big dog". Java based mail clients and OS's have just as many holes as Outlook and 2k. Hackers "in the negative meaning of the word" thrive on the "look what I did" attention. They want the notoriety.
I think it will be interesting to see what MS releases or sets up to protect from these types of intrusions. I'm glad they are using their own software because I think it will make their products better.
By the way,these guys will be caught when they start boasting on their hangouts about what they did. It will make for interesting reading for a while.
