There is no doubt that Google, Facebook, Apple, Microsoft and others are created with help and for benefits of three-letter agencies. But even that does not make them monopolies.

However, Internet (itself created by military), appeared too big to chew for them and flee out of their control. Only then, they had to make that step with creating IT monsters to control at least majority. But Internet is still there and could be easily used for your benefits, not theirs. Problem is that you will not find too much people who know that Internet is not just Google or Microsoft and there could be something else.
