Everyone knows the tale of Brand X getting bought out by some faceless global conglomerate and going to shit, but does the opposite ever happen?
Perhaps 8 or 9 in my opinion - removing background clipboard access in 10 was a Huge defeature.
I jumped from 8 to 13 on my (new) personal devices, so I missed a lot of firsthand experience, but the clipboard thing still affected me by making apps like Google Translate worse.
13 does seem pretty nice in a lot of ways - notifications are even more capable than they were in 8, for example. But I do notice it being more restrictive in some ways too.
