I prefer to think that sounds like the average Cuban citizen is more interested in a quiet life and improving their standard of living more than complaining about political issues.
Please note in case you haven't been never in Cuba that Cubans are known for always says aloud what we thinks in any corner either in political or any other matters.
The math is simple, the Cuban average salary is around $20/month, current public internet rate is $2/hour. So, at least you receive an extra money, either from a family remittance, personal business or in my case from working as a freelance (BTW using Internet), you can't pay for much access time.
By gum! Still with that story about the Cuban secret police in 2016...
I'm Cuban and I'm now in Cuba, university professor, not affiliated to any political organization, and I check HN almost all days and personally I do not feel limited in any way, only by its high cost. In the same way private internet access is not illegal, is just nonexistent as option because most Cubans cannot afford the current costs of Internet infrastructure at home.
What about Unreal 4? I read that they support HTML5 pretty decently by using Emscripten. I really do not know what is their current status on that subject.
