They aren't feigning ignorance. The poster is saying people use the word in different ways from the "standard" definition, and therefore it has become unclear what any particular person means when they use the word. This is not feigning ignorance. It's just like how some individuals now call everything Democrats do in the US socialist, progressive, or leftist even though most Democrats aren't any of those things.
