I disagree. While using another search engine certainly gives google and inventive to improve the search, it doesn't really help them to do it.
People switch services for all sorts of reasons. Fashion, apathy (if, say, they switch computers and it has a different default engine), etc. Dissatisfaction is just one reason, and since the process of leaving is silent, they have little enough way to tell why.
Reporting the trouble to them gives them the reason you're dissatisfied in a way that switching doesn't. Of course, they're always free to ignore it, but at least if they do then switching can be an incentive for them to improve rather than an enigma they have to puzzle out.
There is a legal principal known as Fruit of the poisonous tree. Essentially, any evidence that has been found due to an illegal search, even if it wasn't found during the search itself, is inadmissible.
So if the stolen property was discovered because of the gps, then it is likely inadmissible. The article didn't say one way or another, so it is tough to tell. If it had nothing to do with the gps, then it can still be used in court
Remember also that the judge merely ordered a new trial with the bad evidence excluded. If they still have enough evidence that was discovered independent of the illegal search, he may still be convicted.
Ultimately, there is no better way to defend our rights that to completely bar any evidence that has been found in violation of them. It sometimes has the unfortunate side effect or letting the guilty go free, but so long as police maintain their professionalism and act legally it should be a rare occurrence.
