I'm glad they did this, but it still doesn't handle the FUD about Apple generally slowing down old hardware in the name of planned obsolescence, which people have been tinfoil-hatting about since forever.
The fact is that new OS and software is designed to run on the latest hardware and checked on older hardware to see if it will work at all.
The conspiracy theorists think that Apple has been doing this with their phones since they started making them, and for their computers for decades.
It's horseshit, of course, and I wish the statement had been stronger.
The tinfoil garbage is about like if people complained that game companies were intentionally slowing things down for older graphics cards. No. That's just the natural progression as technology advances.
This is a case where Apple is slowing things down, but doing so to improve the user experience, not make it worse.
You have almost all of reddit and several other idiot websites that have been complaining for years about perceived slow-downs now feeling vindicated over this. And it's complete garbage.
I wish people could separate issues effectively, but that doesn't seem to be in the cards.
