The big story in the news last week was "Elon Musk says deal on hold while verifying twitter's 5% Monthly Active Users stat", or something to that effect.
That's the context this article was published in. It is transparently obvious they are re-using the word "active twitter accounts" to cause confusion with the definition of "active" that has been being bandied around. The post is using such a title as a clickbait, to hop aboard a trend.
I think the title, and lack of significant clarification in the article, make it clearly misleading, and I don't think pedantic "well technically active can have multiple definitions" changes the reality of the situation meaningfully.
