While Mastodon does use AcitivityPub, the survey was about Mastodon specifically, which is unique because the applications you use for publishing to Mastodon are exclusive to Mastodon. I can’t use the Mastodon iOS app to publish directly to my WordPress site. Conflating ActivityPub and any service that uses it is not really accurate, and Sarah did mention ActivityPub and the WordPress plugin you linked in this article.
