Hitting an angle that Jon stated in the podcast (but not in the text above) the desire of the hosts to do shorter shows for lower demand on them and their time. I totally sympathize with what is likely a solid time from them to research and/or prep to cover the topics as well as they usually do. Cutting the time (via fewer topics per show) makes sense and I back that 100%.
The irony for me is the polls where the 2 hour show “wins” along with people actually wanting 2 of those shows per week. Dance, monkey… Dance! 
Considering that this is a free podcast, I am happy with whatever TR decides even if it is at odds with the poll. We don’t know the full demands or what the podcast may be taking away with regard to TR app progress and such. I like the info and entertainment, but if it comes at the cost of TR development, I am happy to give up a bit of listening time each week if it helps that goal.
