This is almost boringly textbook late-stage "monopoly in practice" playing out. Start with an "edge". Get big because edge. Use "big" to sharpen edge further. Use big (and/or edge) to consolidate market. Once sufficiently consolidated and/or controlled, raise costs.
This is what costs getting raised looks like in a monopoly market. Who's gonna stop them.
