Mint used to set Firefox's default search engine a customized (read: craptastic) version of Google that's designed to rake in the ad revenue. I wouldn't have a problem with it if it wasn't utterly useless and ugly as sin. (It looked like the Google site search for webmasters.)
Now the default search engine is DuckDuckGo. I have no idea if they have a revshare agreement with them.
I hear you: it sucked. But no matter how much a default setting might suck, it is still a "setting", as in, it can be changed. Unity got Canonical started down a very slippery slope. I can't imagine they're dog-fooding this crap.
