We currently have this issue with mobile data and it doesn't do a damn thing. Engineers don't optimize for mobile data consumption beyond "download for offline usage," and ISPs don't build additional infra based on consumption: it doesn't affect the industry on any level whatsoever.

OP would need to elaborate on why it would in the first place. Bald assertions need only be met with bald assertions, especially when those assertions have real world examples negating them.
