How do you work with open source?

• Sharing source code and knowledge does not reduce it, but increases it for all

• Quality and openness win, self-promotion does not help

• Business models need to be re-considered

• Define both non-commercial and commercial areas

• Apple, Google, Tesla, DeepSeek, Grok are very successful with this
