Posting a link to some personal information about some person in the news is a stretch to call doxxing in the first place.
(I think it's reasonable to look at that Twitter thread as activist journalism)
Doxxing would be if you posted a picture to imgur and then posted a link to that picture along with personal information about a person depicted, or if you posted personal information about a user here or so (that wasn't already clearly public).
Edit tweet wasn’t deleted
