Not necessarily. In a business like ours (online training) where any additional new customers basically flow through to the bottom line, if I got 20% of my revenue from the EU, and I had to pay a 2% fine now and then, it wouldn't be terrible.
I can see how some slimy businesses would say, "I'm not even going to bother complying - I'll just keep taking revenue off the table and paying the small fees."
