You could sign up to the Beta updates programme. That way you'll get to try out possoible new features before they go live and give Apple devs feedback on them. Apple trials most of its changes this way so if they make it to the next update it's because the feedback they got during beta trials was mostly positive.
The "hundreds of comments" about features that you see here pale into insignificance compared to the millions of users who are not complaining. Apple can't create a custom build for everyone and even if they did just a couple of builds or had lagging builds the cost of maintaining two versions of software are massive. And even then there would be people who don't like it..
Regarding your getting out of Apple products to free you up from, as you put it, arbitrary ridiculous upgrades; I don't know what you plan to do but every product out there changes and upgrades its product on similar lifecyle times. Maybe spend some time on the Android boards first to make sure that it really is all sweetness and light over there.
