Before CU, "issue ads" were constrained not to mention a candidate. They could talk about the issues, and strongly hint at which candidate did what they wanted, but it couldn't instruct you on who to vote for. Now all that's required is a thin fig leaf that you're not actually directly coordinating with the actual campaign. And even that much is never enforced. It almost completely undoes campaign limits.
