It’s not children censoring things. It’s people obfuscating words that may get flagged and have their post removed.

These days software can scan images and videos and not just text, for violations of whatever rules they have.

Like on most of the mainstream platforms just the audible mention of suicide gets you flagged. So people have adopted ways to avoid detection like saying unalive instead of suicide.

This censoring of the word death is not for ethical reasons as you are insinuating.

Basically don’t let it piss you off. Terrible hill to die on.

I hate it too, but it is to prevent their post from getting flagged and/or removed. It's a new form of censorship that came into being from advertisers who don't want their products associated with certain topics. The advertisers then threaten to stop advertising on the platform which caused the platform to automate cracking down on any topic that isn't considered advertiser friendly, regardless of how innocent the word's use is.

When this happens "d֎ath" is inevitable.

As many have sort of pointed out, it's not the children. The censorship comes from grown ups running companies. The result is people who just want to speak freely needing to speak slightly differently.

more than it really should

Yep.
