Well, I perfectly understand why they do it. What I want is to have a way to disable it (even paying for browser) or have an easy way to change settings. With Speed Dial entries I have a way, why can't I change search engines? Moreover, in my case I started hating their partners and surely won't use them, so Opera played bad trick to them.

On another hand I want to have all my programs up to date, but that's really annoying!

1. The partner search engines override my settings I've been using for ages. Of course I know the workaround but I'm tired to do it. You may say that I can change the keyword (actually I did) but there's no guarantee that one day they will override other keywords as well!
2. Speed dial always adds stupid links which are not relevant for me at all. Not a big problem of course, but I guess their next step would be disabling 'X' button for them, trust me. I would also like to have a grid for speed dial and not a ribbon. It used to be like that in the old versions a few years ago and it was just great as I could easily group the links by columns. Another story but let it be
