In app purchase

Now in app purchase is everywhere. But I am sure that it is unnatural. Imagine that you want to buy the TV. They say it comes free. Awesome free TV. But you know dude you can watch it just 2 hours per day. If you want to see it all time please pay some money. Our engineers wil came to you and fix it. This TV can switch channels but only if you pay us. You can also change brightness for a bucks. So what have I tooked ? Something that is not called a TV. That's how I spent my own time to investigate what is locked and what is not. Why not to sell full functional TV for a reasoned price. I can just watch at price and reviews to make my choose and not to download and investigate.
