The ACLU fought Trump's "Muslim ban."

That resulted in lots of funding from the anti-Trump crowd. "Trump derangement syndrome" meant previously unimaginable funding.

They needed to do something with the money, so they staffed up, using the new staff to double down on the Trump-fighting.

Before 2016, there were a few claims that the ACLU was biased toward liberals. Afterward, you'll find many articles even from outlets like the Atlantic and the New York Times lambasting the ACLU as openly partisan. Just do a search for them!

So if this is censorship is intended to keep things safe and liberal, people suppose that the ACLU would support the censorship.

This is exactly what happened. They were flooded with money at the same time they were being flooded with new graduates that had strange ideas about what people shouldn't be allowed to do.
