The definition of disinformation is:

> False information which is intended to mislead, especially propaganda issued by a government organization to a rival power or the media.

And the definition of misinformation is:

> False or inaccurate information, especially that which is deliberately intended to deceive.

As you can see, the definitions aren't relative to some other piece of information. It doesn't mean that some information is incorrect based on some other source of acknowledged correct information.

It means that the intent of the information you were given was to deceive and mislead you, and that the information was thus specifically crafted in a way to do so, generally by being false, inaccurate, cherry picked, fabricated, or manipulated in some way.

In this case, you can see that there are some wealthy people who want to propagate some information in order to mislead people, the deceiving part is that they are not transparent about who they are, and they want to make it look like the information is coming from influencers as part of their own volition, and that the belief is held by a lot of people through trying to manipulate the Twitter recommendations and trending algorithms, making it look like the content is more popular than it really is.

The validity of the content of the tweets doesn't even matter, the misinformation is in the misleading lineage of who is really behind the tweets and what their agenda is, and the false representation of how popular the content is.
