Apple, over time, has developed a reputation for quality and overall experience. One of the things that sets Apple apart from the competition is that it's never in a rush to introduce new features. A company like Samsung introduces a lot of new gimmick technologies every year, without ensuring that they are useful to the consumer or that it delivers the best experience. I'm not saying that every new feature from Samsung is useless and poorly developed, but they don't take as much time as Apple to think about how to implement it. AirTags are a clear example of a product that Apple could have released a year or two ago, but have waited to fine-tune the product's functionality, UI and safety.
It is therefore more surprising when there are significant problems with an Apple product, as they have this reputation for quality and perfection in all aspect of their products. I have the new iPad Pro, and frankly the blooming is not as visible and problematic to me as some people claim. That said, I understand that some are surprised that Apple has allowed to integrate a screen with such a visible limitation. It gives the impression that the finished product was not ready, although honestly the technical limitations of the mini-LED have been known for years and not unique to Apple. I’m not defending the mini-LED though, i think that there is room for discussion regarding the relevance of mini-LED vs, say, OLED. But people associate a much higher standard of quality with Apple and because of that, it makes Apple -gates more frequent.
Finally, I will conclude by mentioning the phenomenon of echo chambers. MacRumors is a forum for Apple users who follow Apple products and rumors very closely. Just because there seems to be a -gate on a few forums on MacRumors doesn't necessarily mean it's a widespread problem. For most of the people who bought the new iPad Pro, I doubt they'll even notice this limitation.
