I write obituaries in my local paper. Or rather, I write news obituaries.
You have to understand something about the news industry - it’s entirely ad-supported. A lot of newspapers have gotten rid of news obituaries (death notices) entirely.
Memorial obituaries are written entirely by the family, and the family purchases ad space (usually at a discounted price, but not always) to run the obituary. Memorial obits are a celebration of life, and serve to commemorate the lives of the loved one who has passed on.
Death notices serve an entirely different purpose - they are there to notify the community that the person has died, and when their services and visitation are. That’s it. They tend to be very impersonal and written in whatever style the newspaper writes in, because they’re written by a clerk or a rookie reporter.
In both cases, however, you’re going to have the family intervening. Most newspapers nowadays only need the funeral home contact information so that they can confirm that the person has, indeed, died (I get a LOT of fake obits submitted here - people think it’s a hilarious joke to place a fake obituary for their friend down at the bar for his birthday) - cause of death isn’t necessary.
Newspapers don’t go out and seek obituaries, as some people seem to think. Newspapers take obituaries that are submitted to them - and not every family wants an obituary. So newspapers have to take what they get from the survivors when it comes to writing an obituary - it’s not like the deceased can do it for themselves.
Nine times out of ten, not listing the cause of death is because of family intervention. The other time it’s because the cause of death is not considered appropriate to list (for instance, the above where grandpa died in a whorehouse - although here that probably wouldn’t be as big a deal, as we have legalized prostitution).
