"It is alleged Microsoft may be contemplating an attack on open source by piling up a bunch of patents for stuff everybody has been doing all along, and will use it to sue Linux out of existence. Let's just suppose they manage to do that. What of it? Could the U.S. federal government force folks to stop using Linux?"
"It appears that Microsoft could negotiate with Apple for licensing payments covering every iPod on the market--and, perhaps, every MP3 player on the market. Nothing of the sort is in the wind, but this case does illustrate the treacherous waters in which invention-rich companies swim."
