Here's a real-world analogy for you.
In the UK we have a transport company called Stagecoach. Now, as in: these days, people have forgotten how Stagecoach started .... but not us, not us ... sorry, wrong franchise
.
I remember Stagecoach when they started, it was 1987(ish), I know because I was in school. Stagecoach had a few buses, and set up as a bus company in towns and small cities. There were small bus companies in those towns and cities already, so what Stagecoach did was to offer free services. Now people being people and wanting to save money where they could, would use the free service from Stagecoach and not the service from the already established bus company that they had to pay for. I mean, if you can get it for free, why wouldn't you?
Sooner or later, the bus company that was already there, went bust. Not enough people were using their buses, they weren't getting the income they needed to stay in business and running costs still had to be paid. Eventually Stagecoach would become the only bus company in town, quite literally. This was Stagecoach's plan. As soon as they were the only bus company in town, and people had no choice but to use their service, Stagecoach started charging, not extortionate amounts, but not as cheap or cheaper than the company they had put out of business. Anyone who tried to set up a new bus service to take on Stagecoach, got run out town, going bust, just as Stagecoach had done to the previous companies. Then Stagecoach would move to the next town or city and do it all over again. In many places now, Stagecoach is the only bus company available.
Does this story sound familiar at all? It should if you've been paying attention.
