There is a big reason why the Apple of today won't follow in the footsteps of the Apple of the 1990s. Actually, there are 150 billion reasons.
Apple doesn't have to worry about bankruptcy anymore. And with that kind of money they can afford to buy tens of millions of parts at a time. Or build new facilities and data centers. Or buy companies and talent. There's no limit to the amount of freedom that much cash can bring.
There's really no comparison between the Apple of the "bad ol' days" and the Apple of today.
But getting back to market share... why is "Android" having more market share such a threat to Apple?
I put "Android" in quotes because it's not really a singular thing. "Android" is made up of hundreds of phones in all shapes and sizes... and price ranges.
Are we surprised that, in India for instance, that an $80 Android phone is more popular than an iPhone that costs 5 times as much?
Of course every Android phone sold means that one less iPhone is sold. But someone who is buying an $80 smartphone wasn't looking at Apple phones at all.
Still though... Apple sells a ton of phones... and expensive phones at that. They sells phones as fast as they can make them. And Apple has developer support, and accessory support, and customer satisfaction.
So like I said earlier... Android gets the "most market share" headline... but it seems like a hollow victory.
Apple in the 1980's also had tons of money. IBM PCs (and WinTel PCs later) were manufactured by hundreds of different vendors as well, in fact a lot of them were garage assemblers who sell less than a thousand units a year. So what? They combined still pushed Apple to an almost distinction.
If Apple carries the same attitude it had in the 1980's and 1990's, as you've illustrated clearly above, ignores the threats until it becomes financially obvious, fails to respond correctly when the trend just starts to signal and when there are still chances to revert it, the "bad old days" could very possibly repeat itself.
