I'm not certain you got the point of my post.
The new lids contain more plastic than the combination of the old lids with a straw. In the discussion I had with my friend who works at Starbucks the new lids are just made out of a plastic form that is more easily recyclable. It was the point of discussion amongst a good amount of people around her (to which her and I then discussed it) concerning the optics to some people of removing straws which were made out of plastic and adding in a lid made from more plastic than the previous lid/straw combination in conjunction with what people normally do with their cups when they are done with them (throw them away versus recycling them).
As far as cold foam drink comment: according to Starbucks the new lids will be eventually used with all iced drinks with the exception of the Frappuccino by 2020.
It's not about the foam and coffee.
Here's a picture of the new lid:
