I think there are two cases we should observe to be able to judge motives here: - What happens to Twitter accounts that are heavily critical of Musk, but do not track him or otherwise lead to real-world harassment/violence? - What happens to a Twitter account that is tracking someone else who isn't Musk?
If Twitter is allowing the former (Musk criticism), and banning the latter (tracking/harassment of non-Musk people), then I think this is fine.
