You make a good point with fatalities. Someone who presents with chronic medical issues that may have contributed to their death, but was infected with COVID at the same time, may be ruled a death due to COVID without consideration of other health risks/factors. If, say, someone presented with COVID, but experienced heart failure, would it be ruled a COVID death?
It's hard to say given we just get a lot of anecdotal evidence. From what I heard in the early days the CDC refused to differentiate someone who died of COVID from someone who died with COVID, and I know a few people who lost family members due to unrelated health issues but found their death certificates said they died of COVID.
A key problem is that the fatality rate is a pretty simple concept - how many people died of it divided by how many people had it. The trouble is we've never known how many people have been infected, other than being confident it's a lot higher than official figures (this isn't entirely unreasonable, given people with no symptoms would have no reason to ever be tested). The other problem is that it's hard to believe the death rate, given the issues that muddy the figures. So we're being told a fraction but we can't know what the numerator is other than it's probably less than we're told, we can't possibly know the denominator and anyone who suggests it's much higher than we're told gets censored, which means just about any figure we're given is all but worthless.
Now it's looking more and more like the fatality rate is far lower than we were first told but apparently we're supposed to go back to hiding under our beds and cowering again because the media decided to start howling some more. Curiously the media doesn't seem to understand that if you present life as if it were a choice between "hide under the bed and shake in fear" or "you will die of COVID", sooner or later people stop listening to anything they say. So here we are now, with people not really listening to what the media says and they really only have themselves to blame. They've cried wolf for too long. Maybe now the wolf really is at the door, maybe it isn't. It's just hard to tell for sure.
