You assume time is free, I assure you screwing around with something costs many people more than the money they made sitting on the toilet that day, so they hand over a couple bucks to make it easy.

You're never going to pick up high school kids with free vs. cheap, but they have low disposable income anyway and a lot of people competing for their small amount of cash. It makes sense to target people who have money but little time, companies that do this seem to do very well.
