In some cases, though, congressional aides appeared disappointed with the information Twitter provided. Some on the Senate Intelligence Committee, for example, fretted Twitter had not done more, and sooner, to patrol its website for Russian misinformation, according to a source familiar with its work.

There’s some good momentum for change with social advertising giants. Will be interesting to see what comes of all of this.
