I think the point is that journalists use twitter, not Trump or grandparents. That Facebook is the drug dealer for grandparents is a distinct problem, pointing it out doesn't negate the harm of twitter.

Which is not a problem in itself. If Twitter has done anything it is lower the distance between journalists and the general population, especially minorities, and it allowed "grassroots journalism" to exist in the first place.
Yes, ordinary blogging existed before Twitter, but only Twitter has the advantage of "going viral".
