The city is beautiful. Climate is great. Low taxation (especially if you're self-employed). Cost of living is way better than in Germany. Quality of food, healthcare and public services is also very good.
Also, if you don't like the leftist policies, you'll love Czech Republic.

It seems to have started following the same modus operandi that made a huge mess in Brazil: sectarian politics, removing 'leftists' from every inch of government institutions and instrumenting them with friends, reverting climate policies, etc. But this is only looking from afar.
Absolutely nothing you're describing about the new Czech government is true. They are not populistic (like governments in Brazil or Hungary).
