Africa is a vast and diverse continent, making it difficult to make such a sweeping statement.
However, even having said that, the statement is simply inaccurate--by any stretch of the imagination.
Africa ranks way below North America and Europe in terms of internet access and quality, with the worst ranked country being Chad. The same is true for
cellular service, with the third worst country in the world being in Africa, next only to Afghanistan and a Central American country.
The more appropriate comparison is with European (especially Western and Northern European) countries. You can look at the same sources above to see how they outrank the United States.
So, your logic/argument works exactly against you.
But, it's not true at all (see above).
In fact, Elon Musk's companies have
benefitted from billions of dollars of subsidies from the U.S. government. So, the net benefit from the government is a positive one, in the case of Tesla. As for the law banning Tesla from selling cars directly, this is due to corporatism, which conservatives support and propagate. (But, eventually the government will get it right on this one, despite the effect of corporatism.)
Internet is now becoming considered a
utility, not a luxury. Any reasonable person can understand this... at least anyone who has any empathy whatsoever for poor people.
