As for Michael J. Saylor, look carefully at the list, it's there:

It is a long list and I asked, I am happy to see him there.
As for Nayib Bukele, he is not on the list. Today, the author of this list has made changes and instead of 500 twitter accounts there are 440. I do not know what this is connected with, perhaps the missing number will be published in the second part of the article.
With what I see, he may not be there but I will expect him to be there one day. Nobody know about his bitcoin holding, if he is a whale he can be more influential. I just like how a country make bitcoin a legal tender.
