If you look at China, they have because of their protectionist policies practically thriving clones of many big US tech company. It seems likely that the same would happened in other regions if some of Google services were blocked.
I am not arguing for protectionism per-se, but more out of a shared concern that wealth (including opportunity, work and power) in the broadest sense should distributed. A few companies dominating prohibit this – Apple has over $260 billions in the bank. Or Amazon having more than half of all online sales.
