Was the manifesto titled 'The Allopathic Complex and Its Consequences', seen here: https://archive.is/7jUsF, actually authored and posted by Luigi Mangione (@LuigiMangione)?

Note that it doesn't include the phrases "These parasites had it coming,” and “I do apologize for any strife and trauma, but it had to be done", contrary to numerous news pieces that reportedly quote the manifesto.

Resolves 'YES' if Mangione authored the above piece. (Regardless of having various drafts and/or multiple manifestos)
