Over on the Wikipedia page for the Marvel villain, Doctor Doom, one finds this paragraph…
In 1969 Marvel announced plans to launch Doom in his own comic book, Doctor Doom. The comic was due for release in September 1969, with the story and penciling by Jack Kirby, and would be the first time a villain had received a solo title. Pressure from parental groups and the adverse publicity caused by the news forced Marvel to cancel the title and pulp the entire print run, with only Kirby's file copy surviving. Kirby's decision to leave Marvel shortly after was influenced to some extent by these events.
This is about 99.3% untrue. Marvel did decide to try a Doctor Doom comic around then and they developed a couple of stories with different writers and artists. One was printed as the lead feature in Marvel Super Heroes #20 (May, 1969) and the rest were discarded for creative reasons. Jack Kirby had nothing to do with any of them. There were no protests over the one book that was printed, nothing was pulped, and Kirby's decision to leave Marvel had nothing to do with all these things that never happened.
Aside from that, it's pretty much accurate.
