linux - RedHat的软件都是开源的吗？

Question

根据GPL协议，RedHat的软件理应都是开源的，网上怎么说红帽有很多私有的软件，这是为什么。。

Answer 1

Redhat itself is open source, so there is CentOS

But some Redhat-specific software should not be included

Answer 2

It means that you can use proprietary software on RedHat, but in fact, at most it is open source software

Answer 3

Under the GPL agreement, the redhat system is open source, but the software is not included. Although there are many open source software on redhat, there are still private customized software. After all, people rely on this to make money!
