I can't speak to every matchup, but I started playing CtM a bit after worlds and can give a few observations from that perspective.
Anarchs who trash cards in HQ can make things problematic. CtM is kind of strapped for recursion, so Maw, Imp, Wanton Destruction, Bhagat, and Ed Kim can make things difficult.
Shapers with Misdirection and saavy play can be almost impossible to hit with Hard-Hitting News. I know some players have gravitated towards a SEA Source based tag punishment package rather than HHN because of this.
Runners with Artist Colony or Shadownet can forfeit your Global Foods before you exchange them.
High Link runners basically laugh off your ICE with the exception of Data Raven and Tollbooth. It doesn't help that Hunting Grounds is a very popular tech card right now.
I've had opponents who mostly stayed on top of trashing the Daily Business Shows, rather than the Bankers and other economy cards and the end result is usually a flooded HQ. If you can trash the DBS without sticking your neck out, it's probably worth it.
