The video explained that clearly. New Keurig coffee machines, in order to bolster their own coffee sales, refuse to operate on non-Keurig cups. By bypassing it, consumers can buy equipment then put whatever they want in it, returning control to the consumer.

They don't just refuse to work with non-keurig k-cups, they refuse to work with version 1 k-cups from the old system.

Sucks to be anyone who bought more than a box before their machine broke.

For what it's worth I appreciate the tldr here since I'm mobile and can't watch the video but am curious none the less.
