ACLU and EFF are two of the last few remaining "Great" American institutions - living up to America's own image of itself.
Here is a fresh Glenn Greenwald writeup on it (which is just one opinion, of course):

It is one thing for an individual in the organization to have a nuanced view of the issue and another thing entirely for the organization to have backed off a maximalist view of the right. I encourage you to read the ACLU's position (which interestingly includes "We’ve called on big social media companies to resist calls for censorship.").
This ruling is the crux of the matter. And ACLU's interpretation (against it) seems very logical. Sadly there's no putting the genie back in the bottle though.
