Blogging at Apple vs. Microsoft vs. Sun

Jim Grisanzio's blog has a nice comparison and compilation of articles on the different policies some of the big high-tech companies have with regards to blogging: Jim refers to David Berlind's ZD Net article in which Berlind expands on how Apple CEO Steve Jobs runs a tight ship. Information leaks are treated as flaws in the system that must be eradicated, using the courts if necessary to protect "trade secrets." Hence, blogging at Apple is not an option unless you want to lose your job or simply tow the party line (any Apple employee bloggers out there who want to respond to or challenge this point?). Meanwhile, over at Microsoft, blogging is a popular sport, and greatly tolerated.
