This book was published in 2010:
It is partially based on an interview with an ex-JW, Jerry Bergman, and, besides other things, contains information on H. C. Covington and his Supreme Court cases. The author (J. J. Henderson) makes this conclusion:
Looking back on the Jehovah’s Witnesses’ literature distribution and permit cases, one thing becomes clear. The Watchtower Bible and Tract Society purposefully changed the laws of the land. The Jehovah’s Witnesses instituted a legal plan that was carefully designed, comprehensive in scope, and carried out by thousands of Jehovah’s Witnesses across the nation. This plan expanded the Supreme Court’s interpretation of the First Amendment, shaped contemporary mass media law, and dramatically influenced organizational litigation. The significance of their achievement can no longer be overlooked. Legal scholars will have to rewrite their books. Lawyers will have to rethink their arguments. Citizens and media professionals might write a letter of thanks to the headquarters in Brooklyn. Because Watchtower lawyers did more than protect the religious practices of its members, they established in law an important ideal for all citizens in a democratic nation — that the flow of information must always be unhindered. For this, we all owe a debt of gratitude to this often-annoying, sometimes-intolerant religious sect.
So don't you think that JW's practices, being "irritating", are somehow beneficial for the society overall?
