So does Apple. Despite this, they are both engaged in rent-seeking (https://en.wikipedia.org/wiki/Rent-seeking), which has a harmful effect on everyone but them.
Imagine if roads weren't public, but were built by a single private company. You have a business that moves goods by truck. You can use the private company's roads, but only if you pay 30% of the profit of your goods to the company that owns the roads. It only takes 2% of the profit to maintain the roads; the other 28% is profit (rent) for the road-owning company.
You could choose not to use the roads. But then the only way to deliver the goods is by parachute (which may be possible, but isn't practical). So you use the roads. But this means you have to jack up your prices to make any profit for yourself. Competing is much harder (tighter margins), and your customers are paying more than necessary. Everyone's life is harder, except for the road company.
