maybe? but you are paying for it with you data and usage, you just don't realize it (in addition to being subsequently manipulated by it); that could also probably considered anti-consumer imho...

  > but people wouldn’t use it.

yep, thats right. thats why i think having a price signal where the actual cost is upfront; now you don't discover later your data is being used against you as a "cost" but consider upfront 'do i really wanna pay for this or do something else' etc

said in another way, i feel like giving the customer upfront knowledge about what something actually costs is more pro-consumer because now we can make informed choices
