Passive-aggressiveness implies avoiding direct conflict. The author of this post refers to Acton not speaking up or making a good argument one way or the other, letting things evolve while resisting passively.

Also, the author is being very direct about what he thinks of Acton's behavior, he's not being passive-aggressive.

The second sentence adds nothing to his argument besides adding in a snide criticism with a trailing ellipse. That's passive aggressive to me.
