To be fair, Bill Gates was not the only one projecting that a global pandemic would happen killing millions. The world is pretty much due for a super virus that is highly transmissible with a high death rate.
All things considered, COVID has a 99.9 percent survival rate. Ebola, on the other hand, has a 50-60 percent survival rate. This could have been a lot worse.
But yeah, Bill Gates gets demonized a lot by the conspiracy theorists, nothing new.
Ebola is not transmitted so easily as Covid19 does. Ebola is existing for a while and it's not moving from Western Africa. When it comes to Gates, conspiracy theories are around him because he is so much promoted by media. Gates thinks that, gates say this etc etc. So he is easy target for theories.
