What good an open source software distribution that you can't legally redistribute because it has proprietary parts?
The whole advantage of free and open source is that I can just fire up as many copies of the operating system as I like, give it to friends, slice and dice it - and never worry!
"Redistributing" is very general. If I made an RPi disk image and handed it to a friend, this is certainly "redistributing".
This isn't like "all commercial rights reserved" which we all understand is reasonable.
A regular user opens themself up to be sued for perceived damages, if they so much as post a screenshot of their 'PIXEL' desktop. or if it is determined they so much as crop or edit the image(s), or resizes it to any size other than "long edge at 1920px".
You cannot use the desktop images if you are a commercial entity (because if you are selling/including Raspbian PIXEL in, or with your Pi product, you violate the PIXEL licensing terms).
You cannot redistribute them period, for any reason, commercial or not. You ( the end user) do not own them, you cannot do with them as you please or even share them (e.g, 'redistribution'), and (you the end user) cannot even use them yourself on your system/Pi/hardware after 10 years, (at which time you are no longer covered under the use license, and you must remove them if they are installed).
If you violate the use/licensing terms, you can be sued for significant damages. You indemnify the rights holder/owner/representative agent/authorized third party against any and all claims (in other words, if you get sued for unauthorized use of the images, you cannot counter-sue for monetary loss, attorney's fees, defamation, etc).
