You're saying that you trust that contract today, or are you saying that you have always trusted that contract?
Its only recently that gmail's contract involved keeping out of your data. I think they also only say they abstain from using your data for targeted advertising, not that they don't use it for other purposes. I haven't read the terms in quite a while though and I could be mistaken.
Great products though. I really do wish I could pay for them in exchange for a real, trustworthy, comprehensive privacy promise.
I use gmail, I'm quite happy to trust that contract.
