I found decades ago that some(few) of the anti JW books would quote WT publication in either a sloppy or misleading way. I did a lot of research pre internet and went to original publications which were easier to find in the 70s and 80s hardcover.
As it was decades ago, I don't have specific examples, but occasionally it happened. I Remember only 2 examples of outright lies told by a supposed former JW. regarding teachings, but mostly I saw ignorant mistakes (calling the KH a church (which JWs used to reflexively correct with a long winded explanation)) . I saw a few sketchy anecdotes and still do occasionally. The commonest issue I found as a young person seeking answers was sloppy quotes that in my semi indoctrinated way, I felt were being deliberately misunderstood. Now I see a lot of things that a non JW would not understand the same way as a JW. That's because JWs are indoctrinated. I didn't understand that at that point. I do now.
Most anti JW literature is more sophisticated now, and there aren't so many people who are pissed off and unhinged a bit like in the late 70s.
No one needs to lie. I think apologists like to go after anecdotal stories because they can't be proved, and they love to go after the trinity, thinking that if they can pull them in with one critical issue, they can keep them, destroying the rest of their teaching by attacking general credibility with trinity issue.
the problem is that the world, especially america, is more post-christian. The WT was trying to convert Christians before. Now they are getting folks who don't really care about religion or they actively oppose it altogether. The game has really changed. No one needs to lie. The Truth is easy to access.
