Is an enlightened dictatorship really so bad?

At this point, Google and Amazon together can manage your entire life for you.  You won't need to go shopping, or join any other websites or buy from any other companies to accomplish anything necessary in life.  And generally, behaving this way is actually cheaper than the alternatives.  Many among us question why this could be considered a bad thing, that the ease of access and convenience these giants inject into our lives outweighs any possible drawbacks of them growing so large.  While my personal opinions lean toward the other side, it is easy to understand the argument they make.  For example, we are in a class in which we discuss the dangers of these conglomerates, yet I am writing this on a Google platform that is likely either using AWS or Azure server space and we use 365 for our University CMS.  Even in the act of discussing the faults and dangers of these platforms we reinforce their hegemony.
