Be careful with assumptions. You might end up using MIT components to which you don't have the patent rights. This is one of the reasons why Microsoft adopted the MIT instead of the Apache license that is legally safer for enterprise.

In regards to Red Hat, you don't get the code available in perpetuity (time is three years for GPL portions) and you can't distribute that code to others when it still contains logos and other trademarks from Red Had inside (CentOS is often the alternative). Effectively you are paying them for a time-limited subscription to use their logo. That's on the fine print inside Red Hat license agreements.

I know this because my job is to make sure open source can be used without bobby-traps.
