I guess the point is that you'd really need to dig into the daily works of the ACLU to perform an accurate assessment of whether they have abandoned their civil liberties roots. This article seems to think that two anecdotes proves that the ACLU no longer does any civil liberties work (hence "RIP"). I think a better thesis of the article is that the ACLU sometimes takes causes that people could interpret as being counter to their initial charter. That's a little different than declaring it dead.
