Have they? There's a fair number of people that don't believe anyone is dying of Covid-19, like these idiots. When there's some actual proof then that'd be more convincing. Just because there are some people ranting about it on the internet doesn't make it true.A lot of people have complained that relatives deaths have been attributed to covid even though they were covid free. Complacency rather than conspiracy on the governments part.
But you miss the main point. A lot of people have been dying, apparently entirely coincidentally at the same time as a large number of people are catching Covid-19. In your world the fact they have positive diagnosis of Covid is just a coincidence or a conspiracy. They're really dying of Lyme disease or excessive accumulation of black bile.
