Should big tech companies like Facebook, Google, and Amazon be considered monopolies and broken up?

Giant monopolies eat the competition. Do we want a thousand little fish store owners all competing with each other so that they will give us the best service and price for their services as a result of that competition, or do we want one giant shark that eats everyone, including their own customers?

The giant shark scenario includes abuses. Giant sharks are not mindful of their customers wants and needs.
