We have some issues with piracy, not only in apps, but also especially in the consumer products. There is tons and tons of merchandise out there, especially in Asia, which is not officially licensed products
Worrying about knock-offs merchandise is the same kind of mistake as worrying about piracy.
Concentrate on providing the best products and services for your customers. Stop worrying about what other people are doing. Unless they are doing what you do better than you do it.
And then, the answer is not to think about how you can sue them or lobby for a law that will allow you to sue them.
The answer is to do what you do better than they do it. Trying to arbitrarily restrict other people’s freedom is admitting that you can’t compete.
