There are somethings which are not expressly said but implied. For example, when you scroll down the list of apps in cellular settings, the list stutters and this list has been stuttering since iOS 9. Its been 2 releases and its never been fixed. This proves Apple is not interested in fixing it.
That's not proof. That you ingesting some information, drawing your own conclusions and labeling it as "proof".
In fact, I was in your exact scenario a little while back. A bug was introduced in iOS 8 or perhaps 7. I don't believe it was fixed until iOS 10. And a late version at that (10.3?). When I reported the issue a few years ago, my ticket was closed as a duplicate. So Apple was aware of the bug, yet it still took years to fix. I can't say why it took years to fix, though I have a number of perfectly valid guesses. But I also can't take their lack of action and extrapolate that into "proof" of anything except they'll fix things when they fix things.
I don't get it. I've been following your ramblings on here for a few years. I honestly can't say I agree with most of what you post. Yet by all appearances, you appear to be a reasonably intelligent person. Intelligent enough that I'm rather shocked you don't get the difference between "guessing" and "proof". Intelligent to the point that I have a hard time believing you truly don't understand the difference. Maybe I'm giving you more credit than I ought to be. Or perhaps you're being deliberately obtuse for some unknown reason. Anyway, just tossing that out there. If there's more to your ignorance on the topic than you're letting on, I'd love to know the reason.
