>It's the arrogance that you inherently think somehow know better than the people that want to consume the service
Hrm, well, yes, to an extent. However, People do do research on the psychology of human happiness and a bunch of other human charistics and we can answer some questions on what will be "best" in the longrun with quite a bit of certainty.
We also know that oftentimes people are just downright wrong about what will make them happy.
Example- we know spending your money on experiences rather than objects will make you happier in the long run.
If you want to read more about the topic I recommend the book "Stumbling on Happiness."
Sometimes we DO know that your choice is wrong for your goals.
Thats just in general, not particularly about this service.
