I would definitely pay for this. Economist, WSJ, NYT, Bloomberg, FT would cost about $200/month for a full subscription to each. I don't read any of them that much to justify that sort of money, but if it was 10-20 for a bunch of articles across them all a la spotify I'd definitely pay for it. I think most people I know would too.

However, they are probably concerned about cannibalising their own subscriptions too much to do it, which sucks.
