Here's a real apology. Compare this to WT's version of apologizing and admitting mistakes:

The successor to Herbert Armstrong (The Worldwide Church of God), Joseph Tkach, Jr., made sweeping changes, perhaps more so than any other leader of a large-scale church movement in history. In part he said:
"Our flawed doctrinal understanding clouded the plain gospel of Jesus Christ and led to a variety of wrong conclusions and unscriptural practices. We have much to repent of and apologize for. We were judgmental and self-righteous—condemning other Christians, calling them "so-called Christians" and labeling them "deceived" and "instruments of Satan."
We imposed on our members a works-oriented approach to Christian living. We required adherence to burdensome regulations of the Old Testament code. We exercised a strongly legalistic approach to church government. Our former old covenant approach fostered attitudes of exclusivism and superiority rather than the new covenant teaching of brotherhood and unity. We overemphasized predictive prophecy and prophetic speculation, minimizing the true gospel of salvation through Jesus Christ. We’ve been wrong."
