Luckily they did not acquire Node.js edit: I should have been more specific.. when an open source project is under a company's wing and it gets acquired, you don't know what can happen, even under MIT. Look at express recently. Since it's the under the Node Foundation now, this is not a big deal. Had it happened a short time ago, there may have been further turmoil in the community.
Given that Node.js has always been MIT licensed, that's impossible. That's one reason why it had a liberal license; just listen to Cantrill's Oracle rants sometime to get a better idea.
So actually all of Cantrill's worries with Oracle exist with Node.js's license. I am sad when I see large free software projects licensed under MIT, we are doing ourselves a disservice by allowing proprietary software to take advantage of the free software we've developed.
