The judge would likely never see the case, because the legal department would make sure it gets escalated to someone who can unfuck the problem before it gets that far.

Suing companies can legitimately be the easiest way to resolve issues, especially where small claims courts exist: It turns the issue into something that they can't "resolve" (for themselves) simply by ignoring and stonewalling you, so it becomes cheaper to actually fix the issue.
