I don't dispute the description of the OP, but the problem is likely that while you're freezing there's another person somewhere in the plane thinking it's too warm. Uneven temperatures across planes are a fact of life. Even in the middle of summer - be prepared for a potentially cold plane by having a jacket or sweater with you.
That's generally a good idea also because of the possibility of diversions. If you fly from 80 degree Milan to 90 degree New York you may think you won't need a jacket, but if there's a medical emergency or other problem you may end up diverting to Shannon, Ireland (or somewhere in the Canadian Maritimes) and might be stuck there for a bit in 60 degree rainy weather.
