Many or most UK PPLs don't read notams. Many don't use the internet. Look at the pilot age demographic data (back pages of FTN) - it is obvious.
There is a huge pilot community out there which has never 'got weather' and never 'got notams'. I know a fair few of them myself. They fly out of strips, mostly. No transponders, of course.
And your show was in Class G. Class G is Class G...
Of course pilots should read the notams... the real Q is: do you want to run adult education classes on how to use a PC, and how to get an internet connection when away from home?
What's basically happened is that over the past decade, flying has caught up with the pilot community, and it will take many years to sort out.
