Things that I noticed after looking at Open and Closed licenses:

1.  (Most) Open licenses are simple and short. It’s very much direct to the point so you know what you are dealing with. Closed licenses have so many terms that just wouldn’t fit in one page using a humanly readable font size, hence the reason people just click Agree.  


2. I browsed through Apple’s Terms of Use and one of the first things I noticed in this document (http://images.apple.com/legal/sla/docs/iOS7.pdf) is that it basically tells you that if you don’t agree in at least one out of their 1xxxxxx terms, you just can’t use your phone which came with the iOS Software and you may return it. 


3.  Open licenses also seem to focus on what you can do with it:

Everyone is permitted to copy and distribute verbatim copies of this license document, but changing it is not allowed. – http://opensource.org/licenses/LGPL-3.0


     Closed licenses tell you everything they won’t let you do:

You also agree that you will not use the iOS Software for any purposes prohibited by United States law, including, without limitation, the development, design, manufacture or production of missiles, nuclear, chemical or biological weapons. – http://images.apple.com/legal/sla/docs/iOS7.pdf

     In other words, they are still the ones in control, not you, even if you have purchased your device.
