The emoji suggestion mechanism seem to be made by someone that have no idea how real people actually use emojis. Emojis are never an illustration of the previous word.
However, instead of clicking the dropdown, you can press ctrl-cmd-space once more to skip to the full picker. However, it's buggy, and half of the time it won't output the emoji I pick there for some reason.
Ah, thanks for that. Yeah, the implementation was always iffy, while the search picks up many alternate names, sometimes it just doesn't show a 1-to-1 match. And well, they could have just implemented the suggestion as part of the full picker, as a first option row, while letting you search and pick the others.
As for the caps lock stuff, now that it's been more hours since the upgrade, it's definitely buggy: sometimes it pops up anywhere on web controls, very far away from where it's supposed to be.
Apple was clear when announcing this that their goal was NOT to block ads. It was to block stuff that a) tracked you and b) caused your surfing to slow down. This is what they're aiming for.
So iTunes sales slowed down when music streaming started to get traction. Apple did away with DRM when the majority of the record companies agreed to. I don't doubt for a second that Universal might have sold music without DRM elsewhere, why denying iTunes the same. The record industry were always afraid of the monopoly situation iTunes was becoming.
