I don't think flu cases 'mysteriously vanished overnight' I think what's happened is that Covid-19 is a much larger threat, so the flu hasn't been getting much coverage at all.
Also in regards to your 'fakery' and already being at herd immunity I've got two points to bring up.
1. If someone has died due to a co-morbidity and you're using that to justify the numbers being 'fake' you're ignoring the fact that Covid is still what killed them. Their previous illnesses were in balance *until* Covid came in and threw everything off.
Look at it this way... If I'm working on a tablesaw and I cut my arm off 95% of the way and then you come over and give it a good yank, am I going to say that you pulled it off and that's how I lost my arm?
2. It may seem like we're at herd immunity but that's because people are going into quarantine and wearing masks which is depriving the virus of possible infection vectors. We're in a pseudo herd immunity because the majority of people are doing the right thing.
