The Society is based on their belief that the New Testament says there should be a "governing" group of Christians like the Apostles and Elders of Jerusalem in Acts chapter 15, and that this group has authority to send "letters" to all the Congregations ordering them to accept certain doctrine and teachings.
I don't agree that this governing group is something God intended for any time period after the Apostles died.
However, this could be open to various interpretations, including the one the Society believes in.
The example quote given by the OP is speaking about direction given during the Great Tribulation, after the events predicted by the Governing Body have come true. If these events never come true, that command doesn't apply.
On the flip-side, the Society has issued many statements saying every Witness must imitate the Noble-Minded Beroeans of Acts 17:11 to make sure the Society is teaching the truth of the Bible.
Does the Watchtower Society, JW.org, and the Governing Body 2.0 still have many issues that can cause them to be considered a cult? Yes, they do, and the sooner they change these, the better.
I'm not defending any of their cult-like practices and beliefs, but I refuse to issue blanket condemnations and bitterness over every single thing they do, even when it is actually an improvement.
