iOS 14 will forget that a third-party app is the default, if the app is updated
If a third-party email app is updated, iOS 14 no longer will keep it as a user-set default, and instead reverts to using Apple's own Mail.

One of the most long-awaited features of iOS 14 was the ability to replace certain default apps such as Apple Mail, with third-party alternatives. Now, following initial problems, a new issue has emerged where iOS will automatically reset the choice of mail app if that third-party one is updated.
Twitter user David Clarke has demonstrated how accepting an update to the Gmail app meant that iOS reverts to using Apple Mail instead.
Since the iPhone was first released, there have been set default apps by Apple, which have always taken precedence over any third-party alternatives. Regardless of which app users choose, if they get a web link in an email, for example, tapping that always started Safari.
From iOS 14 onwards, users have been able to specify that such a link opens in an alternative browser. The same feature allows users to replace, say, Apple Mail with Gmail, too.

It seems that every time an email or browser app is updated on iOS 14, it resets the default settings.

But I guess Apple rather waits to be sued for their behavior first, instead of serving customers.
Oh, and it’s 2020 and Spotify isn’t still working natively on my HomePod.
That's on Spotify...
What a half-baked implementation.
The universal app you mention is available on Android BTW. One would be "Better Open With" which has been available for years. I used it on an old ZTE smartphone.
The numerous problems that Apple's implementation has had, and the many other bugs in other Apple code, indicate abysmal software engineering & testing skills.
But to address your point succinctly, you're wrong. Bugs in code aren't an indication of abysmal software engineering. Statements like that only indicate someone making sweeping generalizations. Bugs in code are an inevitable part of software development. There's no such thing as perfect code. Now, is Apple's code more error prone than it used to be? More error prone than any of their contemporaries? Idk, neither does anyone else. Recency bias may cause one to assume it's worse, but that's opinion not empirical evidence.
My Google files (email, drive, photos etc) go to Google cloud infrastructure.
My OneDrive files go to Microsoft infrastructure.
My Huawei Drive files go to Huawei infrastructure.
Dropbox to Dropbox etc.
I'm not aware of a default cloud option.
When I download a file it goes to the internal storage on my phone (downloads folder or the phone gallery etc).
When I upload a file I get a list of service options to use.
