If a person does not "witness" about their god Jehovah any more, formally or informally, are they still a jw? It depends on when what article you look at. It is a dance around issue. Ask yourself, if you are inactive, do the other jws think you will survive Armageddon if still inactive?

Why did the brother become inactive? He admits: “I started
giving more attention to worldly matters than to spiritual things. Then I
stopped studying, engaging in the ministry, and attending meetings. The next
thing I knew, I was no longer a part of the Christian congregation

Hence, when our activity is banned, it is
generally our preaching and our meetings that are prohibited. “You can be
Jehovah’s Witnesses,” we are often told, “but you may not preach or hold any
meetings.” Yet if we did not preach or hold meetings, we would not
be witnesses of Jehovah God or Christ Jesus, since a witness who does not say
anything is really not a witness at all. (Isaiah 43:10, 12; Acts 1:8)

par. 14 Holding Fast the Public Declaration of Our Hope ***
Under that wholesome counsel by Paul it is very
necessary for each one of us to look after himself. It is not just a
matter of saying, ‘I am one of Jehovah’s witnesses,’ or one’s coming to a
meeting and there sitting quietly. It really is a matter of inspecting
yourself, testing or proving yourself by answering questions in public,
voluntarily or when called upon. How can anyone say he is one of
Jehovah’s witnesses if he does not attend and participate in the meetings of
true worshipers of Jehovah? (John 4:23) How can he say, even to himself, that
he believes the truth of God’s Word if he never expresses that truth to his
brothers?
