Biggest doesn't always mean best.As I remember, Samsung ssd's and lcd panels were the desirable ones in the Macbooks not too long ago. But Apple is far wiser than I, so if they have the confidence in TSMC, they are comfortable in their choice. For we the consumers, I hope it all works out as intended.
In other words, you didn't even read the article where it explicitly claims TSMC was coming along better than Samsung and you don't know the industry at all but still wrote something negative about Apple as usual.
And now you're trying to justify that by writing something vague about "for we the consumers". Sure.
