Apple is getting shafted by very guilty parties
First, Apple does have a house, and yes a house to protect as well as to profit from. Could they spread that profit around a bit? Yes but they did build this house a brick at a time and now they reap a decade of very solid marketing and engineering. Do they have others to thank for that success? Absolutely. But so does MS Office, Amazon AWS and thousands of other companies who have a huge product built partially on the efforts of others and housing it in a marketable machine. Just look at Amazon. And try not to think of what became of all the Malls across the country, or the many bookstores that used to exist that are long gone.
Let's consider the accusers, corporate wise. Microsoft the near "king" of product protection? Windows, Office, countless "business" products who just purchased Blizzard for 70 billion to promote their gaming hegemony. So they have a problem with the Apple store? Right. They just hope your lawyers spend more time on Apple than them and this surely helps that goal.
Then we have Epic, the very founding "poor puppy". Epic hasn't operated a profitable enterprise in its entire history of existence! It is giving software away for FREE, and then complaining that Apple holding back profits from them? For God's sake what soul believes they have "the user" in mind? They are pulling a strategy straight out of the Internet Explorer days. If you can't sell a product profitably you give it away hoping that if you can do that long enough you drive the other guy out of business. Bye bye Netscape. See you Malls - next to that "free shipping with Amazon prime" (another venture that never made the company money but surely did put a lot of other companies out of business).
Attorney Generals? Do they think that free is the way this should all be? I mean the Linux endeavor has surely made few hundred billionaires right? Oh wait, maybe not. Hmm. So do you think Tesla should start giving away cars for the $10K worth of batteries and electric motors in them? And why doesn't Epic take on Steam which seems to keep right on chugging in profit and has done so without worrying about the Apple problem, or the Play store or the Microsoft shop.
To me, Epic is pulling the IE vs Netscape plan and is happily enjoining a lot of people with Robin Hood syndrome whereby they don't actually have to make money until their lawyers have done enough damage to their enemies that they can no longer offer an effective product. Spotify is doing the same thing to everyone except Apple in the music streaming business and also does so without yet making a profit.
The is competition by litigation and while Apple isn't a saint, they are being slammed by parties who don't want you to notice what they are doing. And if you give in to that hype, if you help Epic prevail then you'll be doing the gaming world a huge disservice. Let Epic make and sell a profitable business, prove they are operating on a fair basis with ALL their competitors and then, let them come back and make claims. Right now they are hoping the world believes their lawyers more than their marketing team.
