As long as it isn't mandatory like the Russian Max app, I wouldn't worry. The only reason to dislike it (other than privacy issues) is the money spent to develop it (which has already been spent).

There are plenty of reasons to dislike it. The money spent to develp it. The attention spent to maintain it. The abuse of users' goodwill. Dilution of the FBI's brand with a circa 2008. None of these are good. None of them are, frankly, issues I'm going to personally engage on.
