Problem with doing repairs by apple is that they always go with "let's replace the motherboard"

[SoftTalker → LtWorf]

Because the time spent on diagnosing the specific problem and replacing just the faulty component would cost more.

[serf → SoftTalker]

that's charitable.

I would presume that the world's third largest company by market cap would be attracted to that option because it's the most profitable thing to do.

Yes -- there is a nuance between 'most profitable' and 'most thrifty'.

[astrange → serf]

You don't get to be an extremely profitable company by doing things that cynical people online assume are the most profitable thing to do, since they always pick the most evil option assuming it's most profitable.

[nozzlegear → serf]

How does AppleCare factor into your presumption?

[LtWorf → nozzlegear]

It makes people buy apple?

[kube-system → LtWorf]

There is no viable solution to do component level repairs on high density PCBs at scale.
