You're talking like there are no alternatives to all of these products. There are, and not just from Apple. The reason Google's products are popular is because they're advertised as being "free", and Google has enough resources to run them as loss leaders, while also exerting pressure as a giant corporation and monopoly.

If they happen to disappear tomorrow it would cause a minor disruption in the markets, but the world would quickly adjust, and smaller companies would have a chance at competing. Until a new monopoly pops up, and governments are "forced" to break them up again. The circle of capitalism.
