## 問題清單

* free software (自由軟體) 和 open source (開放原始碼) 兩者的理念有何落差？請以創始人的訴求來解讀，儘量引用第一手材料

- 根據 [Free Software Foundation](https://www.gnu.org/philosophy/free-sw.html.en) 內容中提及
`“Free software” means that the users have the freedom to run, copy, distribute, study, change and improve the software`

- 而 [Open Source Definition](https://opensource.org/docs/osd) 可細分成以下 10 項
1. Free Redistribution
2. Source Code
3. Derived Works
4. Integrity of Author's Source Code
5. No Discrimination Against Persons or Groups
6. No Discrimination Against Fields of Endeavor
7. Distribution of License
8. License Must Not be Specific to a Product
9. License Must Not Restrict Other Software

* 從最初的 Cygnus Solutions (史上首間透過 free software 實現盈利的公司), Red Hat (收購 Cygnus Solutions), 到 IBM (收購 Red Hat 並將其既有業務作為主軸)，請解釋公司如何透過 free software 及 open source 來獲利？請列出相關的論文和報告
