I wouldn't assume. Most Apple users I know conform with their devices one way or another (I used to be one of them myself). This could be just one more thing they can live without but would still rather have than not.
Apple won't decide something based on criticism alone or even based on what people want. They decide based on what will net bigger profit. In this case, you can just as easily guess that Apple has data showing that while overpriced parts, hostile repair policy and lack of upgradability bother everyone, all of these contribute massively to the bottom line and are not enough to drive people away en masse.
However, criticism is still important since it can help in some decisions where it can be the determining factor or the missing nudge towards one direction over the other.
I think this is just down to most people not caring. I like the idea of upgradability as an abstract concept, but didn't necessarily use the options when available.
What you're saying here is more like - yes, everybody knows fast food is bad, so let's stop creating YouTube channels about cooking.
If the product is that reliable, why not offer a 3-5 year warranty?
