Looks like those web filters are not working out very well. Yahoo is accused of helping jail another Chinese writer. Microsoft wins a court ruling in an antitrust case.

Microsoft has already agreed to pay more than $1 billion to settle a number of class-action suits brought under state laws.

The suit largely covered purchases of Windows made in the mid-to late-1990s, as well as application software such as Word and Excel.
