The question was: > why does it matter how it works?
and that's all my comment was intended to answer. Many people here are interested both in the idea of doing something enough to upvote AND are curious how something works. We're not necessarily just consoomers, we're often interested in details, but if I was buying something and wanted to know why I should, the maker should probably be able to answer why their thing is special; in this case, I'm just saying that people on HN are generally interested in how things work.
