100% agree. Two small decisions that enrage me for some reason:
1. Stealing the "+" operator away from searches
2. Making Google+ a (semi) closed platform - when I see a link on HN and I click through and it wants me to login to my google+ account just to view the article, I rage inside.
I always want better search, and I've always been happy with google. But now (for many little things like the two above examples) I really want someone else to come along and bring me better search. I don't like google anymore.
