I stopped using straws when I was about 12 years old. There is nothing I drink as an adult that requires a straw being in it.
Anyway, I’m in agreement with what the other poster here said, it’s a private company and they can do what they want as they will live with any consequences.
As a marketing tool, you tend to finish the liquid a bit faster through a straw than sipping from the glass; then you may decide to have another.
