Then figure out how to achieve that ethically rather than third world sh|thole tactics like retroactive legislation.
The people in PiS did - they initially sought to buy out stakes in the foreign media companies. In some cases it worked, in others it didn't. So they used the law. I find that to be ethical, which is totally subjective and relative anyway. They could've just as easily sent in a bunch of investigators over tax payments or fraud or whatever and kept digging till they uncover some kind of impropriety which they eventually would, or make one up. Or just straight up nationalized it. So yes, relatively, they are and have been taking the more ethical route.
People that have power, wealth, etc. 99% of the time didn't get there by being "ethical." They may pretend to be and spout off some slogans or put up a plaque with some donation amount, but at the end of the day it's all b.s. And actually, it's the ones who claim to be so pure and holy, so ethical, that are oftentimes the biggest crooks.
