Given their crypto functionality uses a third party which has been found to skirt the legal system I'd be a lot more concerned about this integration even if I don't intend to use it.
Keep in mind the stuff you read about is only what has been surfaced so far. Who knows what skeletons are still hiding?
Personally, I don't see any point risking it when there are perfectly viable alternatives such as Firefox. Granted the same guy infected Mozilla, but they stood up and ousted him so credit where credit is due.
