The "rootability" thing can be due to the own efforts from OEMs to lock their bootloaders and stuff, and electronic payments not being possible with a rooted phone - which is a major issue for places where people no longer use cash. And maybe the SD cards thing is because people just don't care anymore about running out of storage (they'd delete their stuff or store it on a cloud service somehow). One of the reasons I wanted a Sony Xperia 1ii (and could get ahold of one of them) was it, but since I do not listen to music from my phone anymore I replaced the SD card with a second SIM card. Whereas the "rootability" thing is actually great in my case, since Sony just gave two years of major Android releases to it - I can use Android 13 thanks to LineageOS and its battery life is even better than with the stock firmware. And with my previous phone, a Sony Xperia Z1, I could make it to go with me for +7 years. But yep, I do wish Android OEMs offered more major releases to their phones.
