By all means bash Murdoch - he would be doing the same to anyone else in his situation.
But I respectfully disagree with most of the criticisms of the Sun. No,it's not preferred reading for techies or Oxbridge dons. It's tailored for mass market reading, and is very popular on building sites.
I suspect that some who are criticizing the Sun have not actually read the thing to any extent. I've put in my time on building sites and read it regularly. It's a good product, technically speaking. Well produced, with a clear editorial voice and well-above-average proof-reading.
The point is, many - possibly most - people who read the Sun wouldn't switch to the Times or the Philosophical Review if the red-tops were banned. They'd just stop reading newspapers altogether.
Personally I prefer what readers here probably consider the lumpen proletariat to get SOME world and political information rather than none. If it takes a delivery vehicle like the Sun to do it, I can live with that.
