All those things don't really matter, the only thing that matters is that you cannot sideload apps in iOS. As long as you can sideload apps in android, it will always have a better reputation than somewhere you cannot.
But even those things you mention, they are all part of a scale, even if android becomes more closed-source it's still miles more open-source than iOS, even if it delays new app submissions it's still doesn't require a mac to develop for, has a choice of IDEs and a dozen other development friendly features that we often take for granted outside iOS development.
And it is ludicrous to suggest that android has the same hardware choice as iPhones just because apple now has mid-range level priced phones. Hardware choice means that some models have replaceable battery, physical keyboard, bendable screens, childproof, waterproof and many more options.
Just resign the app IPA file and you can literally drag and drop it through Xcode onto your iOS devices. Unless you mean pirating apps with sideloading...
When the number of devices number in the billions then of course sideloading could be considered a niche interest.
But for people involved in software development it's extremely useful being able to sideload the latest build of an app to show to stakeholders.
Until it isn't. The moment a popular enough app gets banned by google play store, the use of sideloading will skyrocket. If apple decides to ban Telegram, there's nothing you can do (which it did btw at some point).
The ability to sideload is more important than it's usage, both for your personal freedom and for keeping large companies in check.
Until you discover that for example Android Auto is banned in your whole country, while being completely functional after sideloading the apk. And the only reason why there aren't hundreds of millions people sideloading apps (yet) is relatively slow rate of car upgrades. This is only one example.
