NeonMadman - i hope you are kidding. There is much that they have changed or left out of the library both online and on the dvd's. There are simply too many for all to be fixed or deleted.
No, I'm not kidding. I'm not saying that I approve of what they do, or that I don't think they embellish convention experiences and experiences reported in the publications. I have no doubt that they do, and I think it's reprehensible. However, I was talking about the question of reproducing the text of print publications into digital form via the WT Library whether online or on disc. In that case, I think that the appropriate thing for them to do is to reproduce the text exactly as it appeared in the print publication, without regard to whether the information was later proven to be false, as in the case stated by the OP. If the print publication said such and such, then that's what should be in the WT Library, whether or not it is true. As far as I know, they have done this pretty consistently, with only one exception that I am aware of, namely the notorious 1989 WT magazine that said the preaching work would end in "our 20th century," which was changed to "our day" in the printed bound volume. The bound volume text was then faithfully reproduced in the digital WT Library. You say that there is much that they have changed or left out, but that is the only case I'm aware of, and even in that case, the material appears in digital form exactly as it appeared in the bound volume (though not in the original magazine). The change was made between the two print versions of the same article, not in producing the WT Library. If there have been other cases that I don't know about, I'd have to ask you to provide specifics.
Really, this almost becomes a "damned if you do, damned if you don't" situation for the WTS. Condsider the case in the OP: an experience is published in the print Yearbook that is later shown to be false. Do they publish the same text accurately in the digital Library even though the story is untrue, or do they alter it to expunge the false information? If they do the former, you criticize that they are perpetuating the falsehood. But if they do the latter, they will undoubtedly be criticized for altering the text of the publication to make themselves look better. Which should they do? Given the stated purpose of the WT Library, to serve as a archive of the print publications for reference, I believe that they should maintain the text exactly as it was published, regardless of later developments with regard to the source of the information.
