I transferred the last domain I had that was still registered with Network Solutions, and they sent me a cheery little form letter telling me how sorry they were to see me go and that I could transfer back any time. It was actually well written enough that I felt a little pang of guilt for dumping them. That is, until I remembered that they are evil, influence purchasing, customer hating, monopolistic scumbags who deserve to be run out of business as rapidly as possible.
The Mono Project dumped the GPL for the obscure X11 license to make it easier for corporations to contribute code.
