These people are perfectly able to do it right now, just by buying another device. If you don’t like that something lacks features you think are important, you just don’t buy it. How does it matter to you what other people do with their phone? It’s not like Android is in danger of disappearing or anything
If you’re upset that something you bought does not do something that it was never advertised it could do, and in fact is notorious for not doing, then the problem is squarely on your side. Plenty of people did know what they were buying into.
Complaining is one thing, saying that their users, overall, are unhappy with the product requires at least some serious references and a good narrative.
Nobody here is confused. We know what devices we bought, and we know what they do and don't support today. That's the point. Otherwise there wouldn't be a discussion in the first place to talk about what they can, and likely should do.
And that's what this is - a discussion (on a discussion forum). If you're upset that you people don't share your views, the problem is squarely on your side. Plenty of people can understand and discuss the topic though.
Using vague terms like "the platform" are not useful. What does an operating system like "iOS/iPad OS" have to do with the "iOS/iPad ecosystem"? You're not clear even in your own reply. Please try to be more precise.
I'll assume what you're really asking is from the perspective of Apple since the benefit for users is clear - it'll help make more apps available which has network effects of more Apple devices and usage.
This is part of why they are being forced to allow sideloading in the EU. As it turns out in the real world, the interests of corporations are often at odds with the interests of every day people.
