Choose monopolies wisely as there are several types of monopolies with different implications: 1) Economies of scale monopolies which provide lower costs due to large scale but lack competition. 2) Incremental monopolies which solidify their position over time through small continuous improvements, making change difficult. 3) Network effect monopolies which are hard to compete with as their service becomes more valuable as more people use it. Open systems and data portability are important to allow for competition between potential monopolies.
