No, the argument I am making is:
The Rolling Stone thinks Facebook is providing a defective service (i.e. a service that is net harmful). If you agree with that contention, then you should also agree that Facebook should not offer that service. The comment I was responding to was making the generic argument that: “The problem is too hard. Nobody can make a non-defective solution. Therefore, the provider has no choice except to provide a net harmful service.” That is a flawed argument.
You may also disagree with the premise: “Facebook is providing a net harmful service”, but that is independent of the invalidity of the argument presented which assumed it was providing a net harmful service, but they should be allowed to do so anyways due to the argument presented.
