This is a beautiful quote because it is an example of one industry's bad behavior leading to another industry's bad behavior, upon which the first industry then users the second's similarity to justify themselves. Cars only started doing this because phones made it normal. It's wrong in both cases.
It's similar to when Apple defended it's 30% store cut by claiming it's an "industry standard"... specifically, an industry standard that Apple established.
A sibling comment notes that Steam charged 30% at the time (though some had better deals) but it's worth noting that Steam was not an open platform that anyone could publish on. Much like for consoles, to put a game on Steam you had to have a preexisting relationship with Valve, or try to develop one with no certainty of success. This was also considered a very generous cut because getting on Steam was almost a guarantee of financial success.
Why didn't Steve Jobs go with web distribution of first class web apps or allow Flash on his platform? If they truly wanted to be remarkable, this would have been the future.
The answer is control.
Apple is a cutthroat business just like any other, and their "privacy first" veneer is just a wolf in sheep's clothing. They're playing it up as an attack against Google and Facebook, meanwhile they still phone home about the apps you're running and can shut them off remotely.
Microsoft never taxed software on their platform. Jobs had to invent that business model. It flourished like wildflowers thanks to him.
That was exactly his intent when he announced the iPhone, and he got absolutely obliterated by the internet for it.
