I didn't mean that. At the time the medical company was separate from Google. Therefore the statement was intended to communicate the key point - we're not using your data for other stuff. This is the
spirit of the declaration and the part that we should probably care most about.
The statement unfortunately has a secondary implied promise which Google has broken. But my point is that if we don't trust Google to keep the data separate then the initial promise was meaningless. And if we do then not much has changed.
If Google wanted to do bad things then they would have kept the companies separate to keep their promise superficially.
The wording was poorly thought out but unless you think the reorganisation is going to materially change Google's behaviour then I don't see it as hugely significant.
