ELI5: Why is mobile data so expensive? Is it really costly for the companies?

Why do companies need to throttle speeds or charge large amounts of money??
Are they just run by greedy evil bastards?

Is it expensive to the mobile carriers for data? Yes, it very much is expensive to build, run, and maintain their infrastructure, however, its also super valuable to a consumer, so they can charge a ton of money for it, because you will pay. Mobile service is really profitable.

Throttling is different. It's really meant for 1 main thing, to prevent a very very small amount of users who use a wildly huge amount of data for ruining it for everyone else.  Secondarily, and much less important, is to charge some users more for using more data (this can be really profitable, but its really meant to curb those very few ultra-high users)

Yes they are greedy bastards, just like every capitalist corporation in existence, they exist to make money.
