You're right! That's why it's so urgent to take action against disinformation. I just left a comment with some ideas for what people can do to deal with the Twitter problem. As you just said millions are getting killed. What I suggest could just take a minute or two of your time and it will help slow down the spread of disinformation.
The propaganda caused people not to wear masks or otherwise prevent transmission before a vaccine was available. In a world without this propaganda, more people would be alive today - both the idiots that believed it, but also the innocents whose deaths they caused.
