All the way back in “the 1930s, the ACLU started to engage in work combating police misconduct and supporting Native American rights.” https://en.wikipedia.org/wiki/American_Civil_Liberties_Union So it’s been about far more than free speech for the vast majority of it’s history. And it still defends such causes, one example is even in the article:

“In August 2017, officials in Charlottesville, Va., rescinded a permit for far-right groups to rally downtown in support of a statue to the Confederate general Robert E. Lee. Officials instead relocated the demonstration to outside the city’s core. The A.C.L.U. of Virginia argued that this violated the free speech rights of the far-right groups and won, preserving the right for the group to parade downtown.“

So while it’s scope has increased over time which has created increased internal tension, that’s always been the case. “The A.C.L.U. has in fact often gloried in its internal contentions. It split over decisions to represent the Nazis in the 1930s, the Ku Klux Klan in the 1960s, and the Nazis in the 1970s.”

Frankly the organization has never been filled 100% with defenders of free speech the Twitter age combined with a wider scope has brought this internal tension to the general public. The important work they do is generally in the courtroom which is far more focused.
