I think perhaps you need to consider that how you interpret something may not be how it was intended, nor what it was meant to convey, and often the best way to respond to something that seems to deeply offend you is to first confirm that you understand what the other party was actually communicating.

For example, what you seem to interpret as people finding humor in the indignity of a botched portion of someone's funeral, others might interpret as a cautionary tale about what can happen if people are not careful about how crematoriums are run, and the pain it can cause to loved ones and the indignity it can cause to the deceased when the people shirk the maintenance required by the tools they use to do their job in these industries. In that respect, it's no different than a story where a cemetary did not maintain their backhoe, and the family showed up for a burial and the grave was not dug because the machine broke.

Given how the post was spawned from a someone noting a Crematorium Management System (and the lack of an open source option), I would hazard that a cautionary tale about what might happen if you aren't managing your Crematorium well is how it should have been interpreted.
