Regarding Watson, Konfabulator and Netflix Fanatic:
Watson: Apple told the Watson dev that they were working on, and offered him a job. He was too stupid to take it, and got clobbered.
Konfab: This is an iffy one, I think they probably did copy it to some degree, though at the same time Tiger isn’t actually out, so we still need to see what Dashboard really looks and works like.
Netflix: Cricket worked for Apple, and got hit by their rules regarding ownership of code. It is actually a common thing for technology companies to owm code developed by their employees. The fact that Cricket used internal resources to develop the code, and was selling the app, make Apple seem a bit less evil.
Apple still could do better with their dev. relations, but the examples of issues are not clear cut.
