There is a third option.

1. "Whoops, we didn't think this through."

2. This makes us more money in the end, that's why it's so pervasive.

3. It's difficult to correlate "making more money in the end" with our cancellation policy, so we make a measurement or otherwise tell ourselves a story consistent with (2), even though (2)'s conclusion doesn't truly follow.

This reminds me of topics in government policy, psychology, etc.
