My 3 top reasons
Threat to democracy - especially trying to control the courts
Weakening Poland's position in Europe - Poland should be the natural leader of Eastern Europe but it has lost that role and the moderate democracies like Slovakia, Slovenia, Lithuania etc do not look up to Poland
Renationalization - I'm not opposed to keeping strategic assets in state ownership, but PiS just uses state companies to feed and water an army of untalented cronies
