GPL is suitable for infrastructure software, not good for end-user software like video/audio/music player
Dual licenses is a good method: GPL, open source will help to spread the software. While compony customers want to use this software in their products, but they don’t want their product code to be open source, then they need to pay to keep their products as close source
Currently on the subway to Jiangning. There is a mother with her son, I would say he is around 6 years old. She pulls down his trousers and he is wearing long johns. I thought she must be going to tuck his shirt in, because he can't be having a wee. She pulls out a small plastic bag, the ones like you get in the supermarket on the roll to put the vegetables in. She then takes out his old fella, and he starts to fill a flimsy plastic bag on a very wobbly subway carriage full of people. With one hand holding the bag, with her other hand she tucks him away, pulls up his trousers and buttons him up. She is now sat down hold the dangling, and wobbling bag of wee between her legs on carriage that is increasingly getting more people on board. Then I thought myself I guess that is what is called male privilege.
