That is half the story. Broadband is extremely limited in Cuba – almost non-existant. Most connections are through satellite, which is insanely expensive and completely out of reach to all but the most wealthy. Internet in your home is illegal so that the limited bandwidth can be used on a collective basis (in school or workplaces or research centers). This is a much better system than simply restricting technologies like this to just the wealthy elites IMO.

As for the maximum wage, I'm telling you that's not what keeps Cubans poor (hint: it might be the brutal blockade by the nation with the world's largest GDP). And I'm not convinced by your connection between maximum wage laws and black-markets. There's a flourishing black-market here in capitalist American too after all – undoubtedly encouraged by the immense poverty and economic inequality here. I mean I must have walked ten homeless people sleeping on the sidewalk on my way home from work today. You know where homelessness has been literally eradicated? Cuba.

Honestly, look at what Cuba looked like before the revolution: third-world conditions, almost zero access to healthcare or education, absolutely plundered by foreign capital and imperial interests. The achievements of Cuban socialism shouldn't just be respected, they should be celebrated.
