If they're being acquired it's now Google's data. So the question "Will Nest customer data be shared with Google?" is asking "Will Google share Google's new customer information with Google?"

The absurdity of the question should answer itself.

There will probably be a new customer agreement once the whole thing is finalized.

For many years data was actually siloed between different products within Google (probably by accident) and there was some blowback when Google announced that they were merging all of it. So the concept of internal firewalls does exist, but given that all other Google products were merged I would assume that Nest will be as well.

The concept of internal firewall did exist, until they were accidentally removed that one time.

Why would firewalls between silos continue to exist when they've already been blown away?

This seems bad writing on their part, to be honest. The question makes no sense, the answer just doesn’t sound great.
