It will be interesting to see how the new law will be applied, one never knows how broad the legislation will be.
I'm not sure where you're getting your information from, because Polish sources are saying that it will be directed specifically at the problem of people calling the Nazi German camps "Polish". There's no mention of anything else.

All countries have been running concentration camps.
Including Poland. Nothing unusual, really.
