Why do you assume because I listed the most prominent example of GOSH's censorship, that it was the only one? GOSH also litigated against Canadian author J. E. Somma. In both cases, GOSH settled out of court, and in both cases GOSH enforced a lack of transparency over the settlement as part of the terms. The point of these examples is to demonstrate that GOSH went beyond the bounds of mere royalty collector when they saw the chance, not to demonstrate chilling effect.

Chilling effect is not about the books that survived the gauntlet of publication to make it to the litigation stage; it's about all the ideas that never had a chance to blossom because the threat of copyright enforcement nipped them in the bud. Part of what makes this kind of corporate theft so insidious is that it is impossible to count the works it prevented from existing, or judge the social good they would have done.
