i agree with your view on epics behaviour but the point they make is solid gold

But the car manufacturer don't have a constant cost with maintaining a car the costumer paid for 1,2,3 years ago. If your car breaks down, (usually) you pay from your own pocket.If someone runs over a person in the car you sold to them, the car manufacturer is not responsible. If someone turns that into a bomb, the car manufacturer is not responsible, etc.

Not right. Car manufacturers have recurrent cost for warranty and maintenance, safety and modifications. If you car causes accident, is easy to steal, etc the manufacturer can and usually is subject to a civil action.

For a platform holder, you are liable to everything that goes into your platform. If someone posts something malicious, "It's Apple fault for not having a better moderation for such things!". If porn is posted where it wasn't supposed to, the headline on any paper will be " Explicit Porn was seen in Apple store, with nothing been done for hours". Not only that but you pay a team of a hundred+ engineers to keep updating and improving, not to mention the marketing you have to do to promote said platform, like I said before. And engineers are expensive, especially good ones.

And any store in the world have collaborative responsibility for what is sold there even if they only get a cut on the first purchase.

Again, there is a discussion to be had if the 30% cut is fair or not, but saying that they are not entitled to a cut, when the IOS is not only something they own, but that they fostered and devloped and spent hundreds of millions of dollars into building what it is today? Honestly, the kind of person that says stuff like these are the ones that have never been owned a bussiness, and dosen't know how hard you need to work to make it work aand how hard it is to make it work.

You own the device and paid for it, Apple keep it a hostage in a way that you can only install if they say so. If apple was having any hardship to keep profitable we could discuss this, but that really isn`t the way.

If you are unhappy about it, just go to other platforms. There are alot of platforms that dosen't have a cut and are successful enough(Android, PC in general).

I did, I don`t have an iPhone anymore, they overcharge for the HW and over control the SW. And you just proved yourself wrong with your last paragraph, if plenty of platforms can make a profit without doing what Apple is doing it shows Apple doesn`t need to do it.

That they should get what they want, when they want on other people private propriety?
