I completely agree with you in principle. However, if there are potential damages involved, it's hard to argue that you're not increasing your exposure by delaying or deferring the correction. (Again IANAL and this ain't legal advice.) Lawsuits aren't to be taken on a whim. Even if you ultimately prevail, the affair can change your life, and not for the better. So I can't blame anybody who wants to skip the lawyer and minimize their exposure, even if doing so angers a large number of developers—to whom they have no formal obligation.
