## Why to Open Source?
* No integration overhead 🪢
* No knowledge overhead 🧠
* No strategical overhead 👑
* No compliance overhead 🦺

## Now give real reasons!
Silicon is a **basic commodity**.
_Politicians sometimes forget this..._
* You can go into politics. 🗳️
* You can go into low techs. 🚵
* You can go into free chips. 🎀
**🫵 You can also do the three. 🫵**
