I think it's more likely that while the punishment might be significant it will be more profitable to continue as long as possible violating the law or at least pushing the boundaries as much as possible instead of proactively being compliant.

After a court order they will know exactly where the limits are and tiptoe them as much as possible. If they proactively try to be "overcompliant" they might loose more money in the long run.

It's messed up to be honest. I would prefer harsher punishments, but on the other hand if companies are scared all the time it might have a chilling economic effect so there is a balance to strike as well.
