What this illuminates to me is how I care more in this physical situation ( 

DoorDash

or 

Uber

) than I do when I am buying something via a website using 

Shopify

. Because even the latter there is an opaque wall between consumer's awareness and the costs associated with the service provider. But for some reason in my head the people running Shopify seem less disadvantaged than the ones running under DD or Uber.

You can even see it in the language I used above. One party runs an app, while the other runs under one.
