Secondly, why should Google 'care'? They're not a charity nor do you or anyone else have the 'right' to rank on Google, it's just a search engine and sometimes people forget that. Why you even use the phrase 'honest crust' is beyond me, are you trying to elicit sympathy and make Google look evil? Make an 'honest crust', but don't expect that Google owe you that honest crust, they don't.
If there's one thing that posting on this forum has hammered home to me time and time again, it's that you should be diversifying your traffic sources and never ever be reliant on a particular source, particularly such a public one like Google which is fighting a constant battle with spammers and so has to make endless changes to the SERP. I've never bought a website (yet) but I can tell you that I wouldn't touch one that had more than 40% of it's traffic coming from Google unless I was prepared to risk losing that investment overnight.
