What is the Libertarian point of view on the ACLU?

I’m interested in understanding how self-identified Libertarians view the ACLU. Generally I support them, but there are some issues where I do not agree with their positions. Despite these differences, I support most of the work that they do and believe that they play an important role in light the recent increases in authoritarianism in the US. I agree with the critiques that they have become more partisan in recent years, even though I personally agree with some of these positions.
