Fork

There's a little controversy in the Drupal world, a fork by Nathan Haug, aka QuickSketch. Last week he tweeted:

As the dust begins to settle across the tech industry from the recent acquisition of Sun Microsystems by rival Oracle, a number of projects in the Open Source community, including Drupal, will have major strategic decisions to make that could deeply impact their future success.

Open Source projects have to deal with something most proprietary projects don't: forked projects. What's that? It's when a person or group exercises the terms of an open source license to create a derived version that competes with the original.
