Nobody's talking about this because it's not quite true. Nobody criminalises criticising the elites.
It criminalises those who "founds, supports, or promotes a Nazi, communist, or other movement which demonstrably aims to suppress human rights and freedoms, or incites racial, ethnic, national, religious or class hatred, or hatred against another group of persons". No metions about critisizing. Class hatred is not criticising.

In Czechia we had a communist regime in years 1948-1989. The communist party made nearly the same evil as nazis did. For example:
Just because of different political opinions they executed 248 people, imprisoned 205 000 people (8 000 died there), sent 20 000 people to work camps, and forced 22 000 people to work in technical auxiliary battalions.
Another 450 people trying to escape from the country was killed by our own border patrol.
This communist party used their power to completely forbid other parties, to suppress religion, to control TV, radio newspapers. They controlled who can or cannot study, publish books, or even sing based on people's political views...

The party who did all this is still operating here, proudly carrying the legacy of all this, honoring all the symbols, adoring soviet mass killers. That's the KSČM party who is now complaining about the new law, trying to shift the narrarative to "criticising the elites".

we are hearing these stories again and again: "there was no real communism" -> " we will make a real one this time" -> riot/revolution -> failure of the new regime to achieve goal (inevitable, because the economic model is unviable) -> failure to admit the fundamental error -> looking for "enemies of the people, saboteurs and capitalistic agents" -> executions -> fight for shrinking resources -> MORE executions, concentration camps (gulag), closing borders to prevent flee of population -> further decline -> collapse -> country with devastated economy and exterminated elite (business, scientific, cultural, political, civil society) performs painful conversion back to normal economy system. It always goes approximately that way. As you are from a country which never survived communist regime, you should read more about that.

Again: if you believe that you are more smart and lucky and "this time" (tm) do everything correct, find another place, these countries have already paid a lot for these delusions. Make your success elsewhere, and then we can discuss. And yes, your ”And yes, we will build a world based in equality and freedom - communist - everywhere ✊" is a direct threat for people of Central and Eastern Europe, you should expect them reacting accordingly.

"Capitalist propaganda" is approximately the same nonsense as "propaganda of eating". Except maybe some tribal areas, every real country in the world now relies on market economy as the principal undelying engine.
