so then they shouldn't have done it

If they didn't think it could be hidden, or if they weren't reasonably confident of its success, it shouldn't have been implemented. Everyone should have known back at the end of April that it had no chance of working. The campaign certainly knew. There was no reason to proceed with it beyond that point. If it had been called off, the rules very likely wouldn't have been changed - yet you would have still known about the loopholes and could have used them in 2016 or 2020 when the race was closer. Now the loopholes are closing.
