There is nothing for me to ‘admit’ because I’ve never talked about Apple Silicon being ‘open‘ or ‘closed’.
The concept that you’re arguing (that I don’t agree with) is that Intel Macs are magically ‘open hardware’ and have infinite life and software support. When in reality, they’re hardly different than Apple Silicon. Specifically for an average user. You can keep on hacking Windows 11 on old Intel Macs, but that doesn’t help the millions of people that will treat them just like an iPhone 4S.
Your response and persistence exactly proves my point: you deny Intel or x86_64 are open hardware (I used the words "more or so open hardware" in my initial response; in case you can't read nor comprehend) while Apple Silicon is locked down secret to Apple.
Documentations are plentiful about x86_64. It's proven the case from its existence of over two decades. While GPU in x86_64 is closed more or so, still there are open source drivers from AMD. And there are annual conferences that both AMD and Nvidia will discuss their recent GPU architectures. CPU and GPU are two essential parts for Apple Silicon. Documentation about them is lacking. Apple basically treat them like trade secrets. And we're not there yet for other Apple Silicon features such as media codecs, neutral engines, display engines, matrix multiplication accelerators and etc.
An average user has 70% chance buying a Windows PC, 20% buying a Mac. In that sense, an average user don't treat their PC like an old iPhone at all. An average user benefits from the open and resourceful support on the PC land that extend the longevity of their computers, and the 2nd hand market also flourish.
Before Apple Silicon, MacOS users enjoy similar benefit for Intel Mac due to active mackintosh community and the know-how that they build up. They also benefit from generally higher quality parts from Apple that last even longer. Sort of benefiting from both worlds. Resale values are high because there are sufficient demand that also help the sales of new devices. With Apple Silicon, Apple shut the door and lock it down. Keep it all as trade secrets. Just like previous generations of proprietary Macs. Used market will shrink because everybody see it's useless once MacOS support dropped by Apple. I could see this will eventually impact sales of new devices, and the overall healthiness of the MacOS community.
At the point in time, I even had not sealed the coffin for Apple yet that they won't slowly open up Apple Silicon. But you like the other iSheep or AAPL shareholders or whatever jump in and defend your Apple lord. Unbelievable.
