The numbers are too great. These things have always made the news. Even allowing for click bait you used to see these,stories a few times a year. Now it’s every week.
Unless you have an actual in depth study of death certificates, you’ve got nothing but confirmation bias.
Of course this stuff didn’t used to be news execpt locally pre-internet and even pre-covid, because it didn’t generate clicks like it does post covid. When the click velocity starts to fall, they will start replacing these stories with some other baity genre.
