In my research on this topic I have found no substantial evidence supporting this claim. According to European Journalists Blog Zelenskyy banned 3 cable channels deemed as “pro-Russia” but has not criminalized criticism on the Ukrainian government.
The claim about sending Ukrainians to die is I think more of an opinion than an argument. 7News reported on Ukraine using unmanned vehicles and drones to continue fighting this war. And this war is in self defense and not just to send Ukrainians to die.
The original post was deleted as well so I have no way to fact check the information supporting this claim from that Blue Sky user. And the ad hominem of Zelenskyy being a dictator shows that whoever the op is feels intense bias towards the President of Ukraine.
The only credible statement in this claim is that Ukraine is taking funding and support from other European countries. Here is a list of all the money and resources allocated to Ukraine in the span of this warfare from the European External Action Service website.
