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.
The companies block access to Cube due to sanctions, which there because of Cuba's communist government, which is their fault.
