Generally the way that laws and rules work is that it doesn’t matter how long you’ve been breaking the rule or law, but when you get caught, you have to remedy the problem otherwise what’s the point?
Completely fair, but the fact that this “problem” was so ubiquitous for so long should be factored into the decision of whether or not to issue a recall. Recalls aren’t without negative consequences - huge effort and actual cost, opportunity cost of other things regulators could focus on, and the impact to what it means to the term “recall”.
