The short answer? $2T can buy a lot of secrecy and extensive QA.
The long answer is I don't think either of these statements are necessarily true? Apple products usually leak before their official launch. And as for quality while generally ok... Apple has had some poor launches including: Apple Maps, Safari on Windows, butterfly keyboard mechanisms. And other issues are user unfriendly product design like the mouse that has as charging port on the bottom rendering it unusable. And still more quality issues stem from lack of transparency like Battery Gate.
I personally think Apple has a strong fanbase that overlooks these issues and is quick to forget
