This feel like toll roads to me. I get a government body doesn't want the bill, argues "user pays" and gets a toll road operator to build it and take tolls.

But at some point the toll operator has recouped their initial costs and should be charging miniscule amounts in comparison for upkeep.

Honestly, if banks took 30% of every transaction shit would get real ugly.

Users already pay a substantial amount for their phone. How much does it cost to operate the rest? Given Apple profits... not as much as they are taking.
