IANAL but clause 5 seems to prohibit private modifications by letting 
the original contributor demand to get all modifications created by 
other people.

Clause 6.1 has a termination provision for any intellectual property 
action against the original contributor. The extend of this intellectual 
property has not been defined. If the original contributor violates the 
  copyright of anyone who is using software under this license, the user 
has to terminate the use of this software before initiating action. That 
seems draconian to me.

The bottom red text includes "Non-commercial use is restricted to 
educational use only" which is a use restriction but it isn't clear 
whether this is part of the license or not and this seems to be in 
contradiction with the readme although the license would prevail in this 
instance.
