Funny that I don't sweat inside my silnylon anorak while hiking when it's cold, wet and windy. And I do sweat a lot! I just make sure to adjust the insulation layers (if any) under the anorak so that I don't sweat heavily while moving. I pile on the layers (under the anorak) when I stop, and take them off when I start up again.
Of course I grew up in the days when there was no such thing as breathable rain gear. Maybe that's why I don't object to it. My more recent experience with Goretex and a couple of proprietary "WP-breathable" systems showed me that the main difference between the non-breathable and breathable fabrics was price and weight, and I sweated just as much in the "breathable" stuff. Your mileage may vary, and you're entitled to your opinions, but that has been my experience!
