It legitimately tends to be the cheaper way to regulate. You've basically got two options: 1) give a big warning and hope you get a majority change in the industry because they can see the writing on the wall or 2) change the rules and, as immediately as is appropriate, open a bunch of lawsuits... then spend the next decade in the courts spending immense amounts of money while every one of the offending parties runs a big PR campaign about being singled out to comply with a rule that most of the other companies aren't complying with. Politics is ugly and rarely will the straightforward approach be the easiest and cheapest.
