I saw the original post on X which the DM has turned into a ridiculous clickbait article (shocker). She did not "rage".
Kirstie's follow up to people who moaned was that PK's family used the term "died" in their statement, so she felt BAFTA should have used the same terminology.
Storm in a teacup, especially as the DM are very much known for using the term "died" or "dead" in announcements about famous deaths. I don't remember any news outlet saying "Queen Elizabeth II has passed".
For what it's worth, I hate "passed" or "passed away". I think a family absolutely should choose the words they wish to use as it's personal for them, but that organisations and media should say "has died" as that's factual.
