I think everyone should realize what and who a witness of Jehovah is. Not a person necessarily belonging to any organization.
I witness of Jehovah is one who witnesses and proclaims the truths about Almighty God, his son Jesus Christ, and the hope of the Kingdom, etc..
Therefore, I will always consider myself a Witness of Jehovah in how I conduct my life and treat others in the Christ-like way. However, I will never allow myself to be associated with a man-made religious organization.
There is an account in the Bible (I cannot remember the exact scriptures) where Jesus' Apostles wanted to stop a man from preaching or praising Jesus or God because they felt he did not have the holy spirit or was not one of the Apostles and doing it-their way. Jesus reprimanded them and advise them to let the man preach or praise God because it was a good thing, etc.
My point is that there are many witnesses of Jehovah in the world, not just in the WTS organization.
