They have limited service because they can't afford anything better, and the USA prevents installing additional undersea cables, but only a small number of sites are blocked by Cuba itself, such as a few Spanish language news sites run by Cuban-Americans.
Many more sites are unavailable in Cuba because their USA owners refuse access to Cuba, but that's not Cuba's fault.
They could've easily invested more of that oil money they leeched from Venezuela into infrastructure. They built 1 optic fiber cable over a decade a ago, why didn't they build more all this time? It's always the imperialists fault, isn't it?
I am more powerful than you, and I come to you with a request to act against your own interests in order to serve me. You refuse. The harsh consequences for refusing me that I am about to unleash against you are your fault. I am going to starve you for resources for decades, and any bad outcomes for your economy are your fault. You should not have refused me.
Somewhat of an aside, but its odd to me that "communist government" is considered both unworkably unsustainable while also must be sanctioned in order to be stopped.
